geom_miss_point

geom_miss_point provides a way to transform and plot missing values in ggplot2. To do so it uses methods from ggobi to display missing data points 10\ the same axis.

geom_miss_point(
  mapping = NULL,
  data = NULL,
  prop_below = 0.1,
  jitter = 0.05,
  stat = "miss_point",
  position = "identity",
  colour = ..missing..,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  ...
)

Arguments

mapping

Set of aesthetic mappings created by ggplot2::aes() or ggplot2::aes_(). If specified and inherit.aes = TRUE (the default), is combined with the default mapping at the top level of the plot. You only need to supply mapping if there isn't a mapping defined for the plot.

data

A data frame. If specified, overrides the default data frame defined at the top level of the plot.

prop_below

the degree to shift the values. The default is 0.1

jitter

the amount of jitter to add. The default is 0.05

stat

The statistical transformation to use on the data for this layer, as a string.

position

Position adjustment, either as a string, or the result of a call to a position adjustment function.

colour

the colour chosen for the aesthetic

na.rm

If FALSE (the default), removes missing values with a warning. If TRUE silently removes missing values.

show.legend

logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes.

inherit.aes

If FALSE, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. borders.

...

other arguments passed on to ggplot2::layer(). There are three types of arguments you can use here:

• Aesthetics: to set an aesthetic to a fixed value, like color = "red" or size = 3.

• Other arguments to the layer, for example you override the default stat associated with the layer.

• Other arguments passed on to the stat.

Note

Warning message if na.rm = T is supplied.
