A significant new feature in this release is the support of additional model fitting functions, both explicitly and by handling missing methods and values more gracefully. Another important enhancement is a more flexible approach to the filtering of peaks and valleys using height and depth thresholds, which improves the detection of prominent or major (true?) peaks in noisy data by reducing or preventing “false positives”.

This is a soft code breaking change affecting the rendering of model equation labels in some plots.
check_poly_formula() and use it in stat_poly_eq() and stat_quant_eq() to validate that the user-supplied model formula is a polynomial with terms in order of increasing powers, except when output.type = "numeric". If not validated, NA is returned as formatted character string for the equation label.stat_poly_eq(), stat_ma_eq(), stat_quant_eq(), stat_correlation(), and stat_multcomp() were in part reimplemented, introducing small visual changes in the formatting of labels, including changes in the default number of digits in very few cases.stat_poly_eq(), stat_ma_eq(), stat_quant_eq(), stat_correlation(), and stat_multcomp().ggpmisc.small.p, ggpmisc.small.r and ggpmisc.decreasing.poly.eq.

This is a code breaking change, preceded by a long deprecation period.

This has changed in this version as formal parameter mf.values has been renamed fm.values and variable mf_tb in values returned by statistics renamed fm.value. Although these are code breaking changes, they are likely to cause difficulties only in isolated cases as defaults rarely need to be overridden.use_label() that greatly simplifies assembling and mapping combined labels from the values returned by stat_poly_eq(), stat_ma_eq(), stat_quant_eq() and stat_correlation().fm.tb.type, fm.class, fm.method, and fm.formula.chr to the data returned by stat_fit_tb(), and rename mf_tb into fm.tb for naming consistency.fm.class, fm.method, and fm.formula.chr to the data returned by all other textual-annotation statistics statistics based on model fitting.stat_correlation().

stat_peaks() and stat_valleys(). They could return wrong values for peaks and valleys if the rows in data in the ggplot object were not sorted by the value of x for all arguments to span different from null.This is a minor update for compatibility with ‘ggpp’ (>= 0.4.3) and fixing a wrong version number for ‘gginnards’ in DESCRIPTION.
An issue raised in GitHub and a question in StackOverflow asked for the possibility of changing how fitted lines are plotted based on the goodness of the fit. In addition an old question in StackOverflow highlighted the need of more intuitive support for annotations based on stats::cor.test(). We implemented these requested enhancements and continued adding support for flipping of statistics through parameter orientation as implemented in ‘ggplot2’ since version 3.3.0.
Update stat_poly_line() to optionally add columns n, p.value, r.squared , adj.r.squared and method to the returned data frame. This statistic no longer supports fitting of splines with methods such as loess . This could potentially break user code, in which case the solution is to use stat_smooth().
Update stat_ma_line() to optionally add columns n, p.value, r.squared and method to the returned data frame. (As only a slope can be fitted, adj.r.squared is irrelevant.)
Update stat_quant_line() and stat_quant_band() to optionally add n and method columns to the returned data frame. (No exact equivalent of r.squared exists for quantile regression.)
Update stat_fit_residuals() to optionally return weighted residuals.
Update stat_peaks() and stat_valleys() to allow flipping with new parameter orientation.
New function stat_correlation() to annotate plots with correlation estimates, their P-value, a test statistic and n computed with stats::cor.test(). Numeric values are included in the returned data frame to facilitate conditional display.
Add statistics stat_ma_line() and stat_ma_eq() implementing model II regression based on package ‘lmodel2’ (major axis, standard major axis, and ranged major axis regression). Methods coef(), confint() and predict() for fit objects returned by lmodel2::lmodel2() are also implemented and exported.
Removed setting of fill to light blue in stat_quant_band() as there is no safe way of overriding the geom’s default.
Fix major bug in stat_poly_eq() and stat_quant_eq() affecting only some R builds, reported and reproduced for Linux. (Reported by Flavio Lozano-Isla, T. BruceLee and Lewis Hooper, debugged with the help of Mark B. Neal.) Reported to affect versions 0.4.0, 0.4.1, 0.4.2 and 0.4.2-1.
Fix a bug remaining in 0.4.2, that could result in after_stat() not being found. (Reported by Prof. Brian Ripley and Michael Steinbaugh.)
Changes to Depends, Imports and Suggests, to solve errors and/or to avoid dependencies that are not needed. As a consequence package ‘broom’ is no longer automatically installed as a dependency of ‘ggpmisc’ and if used, will need to be explicitly installed by the user. Several examples are now run only if the necessary packages have been installed (Prof. Brian Ripley, Uwe Ligges and members of the CRAN’s team are thanked for package quality control).
The suggestion from Mark Neal of adding support for quantile regression partly addressed in ggpmisc 0.4.0 has lead to additional enhancements in this version. The idea of supporting confidence bands for quantile regression came from Samer Mouksassi who also provided code examples. Additional suggestions from Mark Neal, Carl and other users have lead to bug fixes as well as to an interface with better defaults for arguments (see issue #1). Some other enhancements are based on my own needs or ideas.
rlm and for fit function objects in stat_poly_eq().stat_poly_eq() and stat_quant_eq() with formula = x ~ y and other models in which the explanatory variable is y in addition to models with x as explanatory variable (this was already supported but the defaults for eq.with.lhs and eq.x.rhs were hard coded needing manual override while they are now set dynamically depending on the formula).stat_poly_eq() and stat_quant_eq() so that they pass to the geom by default a suitable value as argument to parse depending on output.type (enhancement suggested by Mark Neal in issue #11) and so that the default output.type is "markdown" if the argument passed to geom is one of "richtext" or "textbox", improving compatibility with package ‘ggtext’.stat_poly_eq() and stat_quant_eq() so that when output.type = "numeric" they return the coefficient estimates as numeric columns in data (problem with coefs.ls column in data when using facets reported by cgnolte in issue #12).stat_poly_eq() adding support for optional use of lower case r and p for and -value, respectively.stat_poly_eq() and stat_quant_eq() resulting in mishandling of formulas using the `+ 0` notation to exclude the intercept (reported by orgadish in issue #10).stat_poly_line(), which is a new interface to ggplot2::stat_smooth() accepting formula = x ~ y and other models in which the explanatory variable is y rather than x or setting orientation = "y". In contrast to ggplot2::stat_smooth(), stat_poly_line() has "lm" as default for method irrespective of the number of observations.stat_quant_line() which is a merge of ggplot2::stat_smooth() and ggplot2::stat_quantile() accepting formula = x ~ y and other models in which the explanatory variable is y rather than x or setting orientation = "y" to fit models with x as explanatory variable. This statistic makes it possible to add to a plot a double quantile regression. stat_quant_line() supports plotting of confidence bands for quantile regression using ggplot2::geom_smooth() to create the plot layer.stat_quant_band() which plots quantile regressions for three quantiles as a band plus a line, accepting formula = x ~ y and other models in which the explanatory variable is y rather than x or setting orientation = "y" to fit models with x as explanatory variable. By default the band uses "steelblue" as fill, to distinguish them from confidence bands.rq, robust regression rlm, and resistant regression lqs and function objects to stat_fit_residuals() and stat_fit_deviations() .stat_fit_residuals() and stat_fit_deviations() with formula = x ~ y and other models in which the explanatory variable is y in addition to models with x as explanatory variable.weights to returned values by stat_fit_residuals() and stat_fit_deviations() and add support for the weight aesthetic as their input for parameter weights of the model fit functions.stat_poly_eq() and stat_quant_eq() so that by default they keep trailing zeros according to the numbers of significant digits given by coef.digits. A new parameter coef.keep.zeros can be set to FALSE to restore the deletion of trailing zeros. Be aware that even if the character label for the equation contains trailing zeros, if it is parsed into R an expression (as it is by default) the trailing zeros will be dropped at this later stage. Trailing zeros in the equation will be rendered to the plot only if output.type is other than "expression". Equations and other labels may render slightly differently than in previous versions as now sprintf() is used to format all labels.stat_poly_eq() and stat_quant_eq() that resulted in bad/non-syntactical character strings for eq.label when output.type was different from its default of "expression".Package ‘ggpmisc’ has been split into two packages: ‘ggpp’ containing extensions to the grammar of graphics and ‘ggpmisc’ containing extensions related to plot decorations based on model fits, statistical summaries and other descriptors of the data being plotted. Package ‘ggpmisc’ depends on ‘ggpp’ with no visible changes for users. Package ‘ggpp’ can be loaded instead of ‘ggpmisc’ when only the extensions it contains are needed. Package ‘gginnards’ containing tools for editing ggplot objects as well as tools for inspecting them is an earlier spin-off from ‘gpmisc’.
The changes in this version stem for users’ questions and suggestions. Many thanks!
Add stat_quant_eq() based on quantile regression as implemented in package ‘quantreg’. (enhancement suggested by Mark Neal)
Add n.label and n to the values returned by stat_poly_eq()and stat_quant_eq(). (enhancement suggested by a question from ganidat)
Add r.squared, adj.r.squared, p.value and n as numeric values returned in addition to the corresponding character labels when stat_poly_eq() is called with output.type other than numeric. Similarly for n and rho in the case of stat_quant_eq(). (enhancement suggested by a question from Tiptop)
Fix bug in stat_poly_eq() leading to empty returned value when data contains too few observations to fit the model. (reported by ganidat)
Add support for quantile regression rq, robust regression rlm, and resistant regression lqs and function objects to stat_fit_deviations().
geom_plot().stat_poly_eq().stat_poly_eq() that resulted in no labels being displayed for any group when one group has too few distinct x-values to fit the polynomial (reported by user 5432156 “ganidat” in StackOverflow).geom_linked_text(). Except for the drawing of segments or arrows this new geometry behaves as ggplot2::geom_text() . Note: Segments and arrows are drawn only if the position function used returns both the repositioned and original coordinates.position_nudge_centre() and position_nudge_line() compute the direction of nudging and return both the nudged and original positions.position_nudge_to() nudges to new user-supplied position(s); position_nudge_keep() nudges to position(s) based on user-supplied position shift. These functions return both nudged and original position(s), which makes possible to draw connecting segments from text labels to the original position.stat_fit_glance() , stat_fit_augment() , stat_fit_tidy() and stat_fit_tb() now import the tidiers from package ‘generics’ instead of from ‘broom’. As a result, users must now explicitly load the package where the methods to be used are defined, such as ‘broom’ or ‘broom.mixed’ or define them before calling these statistics.glance.args to stat_fit_glance() , parameter tidy.ars to stat_fit_tidy() and stat_fit_tb() and parameter augment.args to stat_fit_augment() as some specializations of broom::glance(), broom::tidy() and stat_fit_augment() accept arguments specific to a given fitting method.stat_fit_tidy() would fail with quantreg::rq() and any other fit methods that do not return by default standard error estimates for parameter estimates (Thanks to Mark Neal for reporting the problem).stat_fit_glance(), stat_fit_augment() and stat_fit_tidy() to ensure compatibility with cor.test() and other functions that require an object rather than a quoted expression as argument for data .p.digits to stat_fit_tb().try_tibble.ts() and try_data_frame() did not handle correctly the conversion of dates for some time series, which also could affect ggplot.ts().stat_peaks() and stat_valleys() generated wrong labels if a Date object was mapped to x (the bug did not affect POSIX or datetime, and was obvious as it resulted in a shift in dates by several decades).stat_fit_tb() to support renaming of terms/parameter names in the table (Suggested by Big Old Dave and Z. Lin). In addition implement selection, reordering and renaming of columns and terms/parameters using positional indexes and pattern matching of truncated names in addition to whole names. Improve formatting of small P-values.stat_fmt_tb() to support the same expanded syntax as stat_fit_tb().stat_dens1d_filter(), stat_dens1d_filter_g() and stat_dens1d_labels(), to complement existing stat_dens2d_filter(), stat_dens2d_filter_g() and stat_dens2d_labels().stat_dens2d_filter(), stat_dens2d_filter_g() and stat_dens2d_labels() adding formal parameters keep.sparse and invert.selection, as available in the new 1D versions.stat_dens2d_labels() to accept not only character strings but also functions as argument to label.fill as the new stat_dens1d_labels() does.ggplot2::annotate() adding support for aesthetics npcx and npcy.stat_summary_xy() and stat_centroid().stat_poly_eq() to support labelling of equations according to group.output.type "markdown" in stat_poly_eq() usable with geom_richtext() from package ‘ggtext’.geom_table_npc().stat_poly_eq().stat_poly_eq().This version implements some new features and fixes bugs in the features introduced in version 0.3.1, please do rise an issue if you notice any remaining bugs! Some reported weaknesses in the documentation have been addressed. This updated version depends on ‘ggplot2’ (>= 3.2.1).
Add support for volcano and quadrant plots of outcomes.
Add geometries geom_vhlines() and geom_quadrant_lines().
Add convenience scales scale_x_logFC() and scale_y_logFC() for data expressed as fold change.
Add convenience scales scale_x_Pvalue(), scale_y_Pvalue(), scale_x_FDR(), scale_y_FDR().
Add convenience scales scale_colour_outcome(), scale_fill_outcome() and scale_shape_outcome() for data expressed as ternary or binary outcomes.
Add conversion functions outcome2factor() and threshold2factor() to convert vectors of numeric outcomes into factors with 2 or 3 levels.
Add conversion function xy_outcomes2factor() and xy_thresholds2factor() to combine two vectors of numeric outcomes into a 4-level factor.
Improve support for model-fit annotations.
Update stat_poly_eq() so that optionally instead of text labels it can return numeric values extracted from the fit object.
Document with examples how to pass weights and covariates to statistics based on methods from package ‘broom’. Highlight the differences among stat_poly_eq() and the stat_fit_xxx() statistics implemented using package ‘broom’.
Revise stat_apply_fun() to allow simultaneous application of functions to x and y aesthetics, and handling of diff() and other functions returning slightly shorter vectors than their input.
Support in stat_fit_tb(), stat_fit_augment(), stat_fit_tidy() and stat_fit_glance() the use of character strings as position arguments for parameters label.x and label.y when using geoms based on x and y aesthetics in addition to when using those taking the npcx and npcy aesthetics.
This is a major update, with a few cases in which old code may need to be revised to work, and many cases in which there will be subtle differences in the positions of labels used as annotations. The many new features may still have some bugs, please do rise an issue if you notice one!
Version requiring ‘ggplot2’ (>= 3.1.0).
Add new geometries, several of them accepting x and y in npc units through the new aesthetics npcx and npcy, allowing positioning relative to plotting area irrespective of native data units and scale limits. These geometries are useful on their own for annotations in particular they allow consistent positioning of textual summaries. By default they do not inherit the plot’s aesthetic mappings making their behaviour remain by default in-between that of true geometries and that of annotate().
geom_text_npc() and geom_label_npc() using aesthetics npcx and npcy.geom_table_npc() using aesthetics npcx and npcy.geom_plot() and geom_plot_npc() which can be used to add inset plots to a ggplot.geom_grob() and geom_grob_npc() which can be used to add inset grobs to a ggplot.geom_x_margin_point(), geom_y_margin_point(), geom_x_margin_arrow() and geom_y_margin_arrow() which behave similarly to geom_hline() and geom_vline() but plot points or arrows instead of lines. Add geom_x_margin_grob() and geom_y_margin_grob() with similar behaviour but for adding grobs.geom_table() and depended on the old default of inherit.aes=TRUE.stat_apply_panel() and stat_apply_group().stat_fit_glance() and improve diagnosis of unsupported input. Replace bad example in the corresponding documentation (workaround for bug reported by Robert White).Version requiring ‘ggplot2’ (>= 3.0.0), now in CRAN. Low level manipulation and debug methods and functions moved to new package ‘gginnards’ available through CRAN.
stat_poly_eq() (fixing bug reported by S.Al-Khalidi).stat_fit_tb().stat_fmt_tb() for formatting of tibbles for addition to plots as tables.stat_quadrat_count() into stat_quadrant_count() (miss-spelling).Non-CRAN version with additional functionality, but requiring the development version of ‘ggplot2’.

geom_table(), a geom for adding a layer containing one or more tables to a plot panel.stat_fit_tb() a stat that computes a tidy tabular version of the summary or ANOVA table from a model fit.CRAN version
Add stat_quadrat_count() a stat that computes the number of observations in each quadrant of a plot panel ignoring grouping.
Fix bugs, one of which is code breaking: the names of returned parameter estimates have changed in stat_fit_tidy() now pasting "_estimate" to avoid name clashes with mapped variables.
stat_fit_tidy() so that it returns p-values for parameters, in addition to estimates and their standard errors.geom_debug() adding missing default arguments.delete_layers(), append_layers(), move_layers(), shift_layers(), which_layers(), extract_layers(), num_layers(), top_layer() and bottom_layer().Add stat_fit_tidy() implemented using broom::tidy(). Makes it possible to add the fitted equation for any fitted model supported by package ‘broom’, as long as the user supplies within aes() the code to build a label string. Update user guide.
Fix bug in stat_poly_equation() eq.x.rhs argument ignored when using expressions.
try_tibble() and try_data_frame() which made them fail silently with some objects of class "ts" in the case of numeric (decimal date) index for time. In addition lack of special handling for classes "yearmon" and "yearqrt" from package ‘zoo’, lead to erroneous date shifts by a few days.ggplot.ts() and ggplot.xts().label.fill in stat_dens2d_labels() from NA to "".stat_dens2d_labels() useful.Add stat_dens2d_labels(), a statistic that resets label values to NA by default, or any character string supplied as argument, in regions of a panel with high density of observations.
Add stat_den2d_filter(), a statistic that filters-out/filters-in observations in regions of a panel with high density of observations. These two statistics are useful for labeling or highlighting observations in regions of a panel with low density. Both stats use a compute_panel function.
Add stat_den2d_filter_g(), a statistic that filters-out/filters-in observations in regions of a group with high density of observations. This statistics is useful for highlighting observations. It uses a compute_group function. They use internally MASS:kde2d to estimate densities and default values for parameters are adjusted dynamically based on the number of observations.
stat_poly_eq().try_data_frame() to return an object of class "tibble" and add try_tibble() as synonym.stat_poly_eq().stat_poly_eq().geom_debug().stat_fit_augment().Enhance stat_poly_eq() so that 1) position of labels according to npc (relative positions using normalized coordinates), as well as by named positions "top", "bottom", "right", "left" and "center" is now implemented; 2) when grouping is present, suitable vjust values are computed to automatically position the labels for the different groups without overlap. Default label positions are now relative to the range of each panel’s and scales, eliminating in most cases the need to manually tweak label positions.
Add stat_fit_glance() uses package ‘broom’ for maximum flexibility in model function choice when wanting to add labels based on information from a model fit, at the expense of very frequently having to explicitly set aesthetics, and always having to add code to do the formatting of the values to be used in labels. Label position is as described above for stat_poly_eq().
Add stat_fit_deviations() for highlighting residuals in plots of fitted models. This statistic currently supports only lm() fits. By default geom “segment” is used to highlight the deviations of the observations from a fitted model.
Add stat_fit_residuals() for plotting residuals from a fitted model on their own in plots matching plots of lm fits plotted with stat_smooth() even with grouping or facets. This statistic currently supports only lm() fits. By default geom “point” is used to plot the residual from a fitted model.
Add preliminary version of stat_fit_augment(), which uses package ‘broom’ for maximum flexibility in model function choice, to augment the data with additional columns of values derived from a model fit.
stat_poly_eq().stat_poly_eq().stat_poly_eq().stat_debug_panel() and stat_debug_group() so that they can optionally print to the console a summary of the data received as input.geom_debug(), a geom that summarizes its data input to the console, and produces no visible graphical output.stat_poly_eq().try_data_frame().stat_poly_eq() changed to include the lhs (left hand side) of the equation by default.Add function try_data_frame() to convert R objects including time series objects of all classes accepted by try.xts() into data frames suitable for plotting with ggplot().
Update stat_peaks() and stat_valleys() to work correctly when the x aesthetic uses a Date or Datetime continuous scale such as ggplot() sets automatically for POSIXct variables mapped to the x aesthetic.
stat_debug() as stat_debug_group() and add stat_debug_panel().stat_peaks() and stat_valleys() (these are simpler versions of ggspectra::stat_peaks() and ggspectra::stat_valleys() for use with any numerical data (rather than light spectra).
