Box-arrow diagrams for multi-state models.

Source: R/plot.Hist.R
plot.Hist.Rd

Automated plotting of the states and transitions that characterize a multi states model.

Usage

# S3 method for class 'Hist'
plot(
  x,
  nrow,
  ncol,
  box.width,
  box.height,
  box.padding,
  xbox.position,
  ybox.position,
  stateLabels,
  arrowLabels,
  arrowLabelStyle = "symbolic",
  arrowLabelSymbol = "lambda",
  changeArrowLabelSide,
  curved,
  tagBoxes = FALSE,
  startCountZero = TRUE,
  oneFitsAll,
  margin,
  cex,
  rasta = FALSE,
  verbose = FALSE,
  ...
)

Arguments

x

An object of class Hist.

nrow

the number of graphic rows

ncol

the number of graphic columns

box.width

the widths of the boxes on the scale from 0 to 100

box.height

the heights of the boxes on the scale from 0 to 100

box.padding

how much room there should be between the label and the border of a box. Two values on the scale from 0 to 100: the first for the horizontal x-direction and the second for the vertical y-direction padding.

xbox.position

the x box positions (left lower corner) on the scale from 0 to 100.

ybox.position

the y box positions (left lower corner) on the scale from 0 to 100.

stateLabels

Vector of names to appear in the boxes (states). Defaults to attr(x,"state.names"). The boxes can also be individually labeled by smart arguments of the form box3.label="diseased", see examples.

arrowLabels

Vector of labels to appear in the boxes (states). One for each arrow. The arrows can also be individually labeled by smart arguments of the form arrow1.label=paste(expression(eta(s,u))), see examples.

arrowLabelStyle

Either "symbolic" for automated symbolic arrow labels, or "count" for arrow labels that reflect the number of transitions in the data.

arrowLabelSymbol

Symbol for automated symbolic arrow labels. Defaults to "lambda".

changeArrowLabelSide

A vector of mode logical (TRUE,FALSE) one for each arrow to change the side of the arrow on which the label is placed.

curved

The curvature of curved arrows via diagram::curvedarrow. Experimental. Values between 0 (no curvature) and 1 are meaningful.

tagBoxes

Logical. If TRUE the boxes are numbered in the upper left corner. The size can be controlled with smart argument boxtags.cex. The default is boxtags.cex=1.28.

startCountZero

Control states numbers for symbolic arrow labels and box tags.

oneFitsAll

If FALSE then boxes have individual size, depending on the size of the label, otherwise all boxes have the same size dependent on the largest label.

margin

Set the figure margin via par(mar=margin). Less than 4 values are repeated.

cex

Initial cex value for the state and the arrow labels.

rasta

For construction purposes.

verbose

If TRUE echo various things.

...

Smart control of arguments for the subroutines text (box label), rect (box), arrows, text (arrow label). Thus the three dots can be used to draw individual boxes with individual labels, arrows and arrow labels. E.g. arrow2.label="any label" changes the label of the second arrow. See examples.

Note

Use the functionality of the unix program `dot' http://www.graphviz.org/About.php via R package Rgraphviz to obtain more complex graphs.

## A simple survival model

SurvFrame <- data.frame(time=1:10,status=c(0,1,1,0,0,1,0,0,1,0))
SurvHist <- with(SurvFrame,Hist(time,status))
plot(SurvHist)
#> Warning: The dimension of the boxes may depend on the current graphical device
#> in the sense that the layout and centering of text may change when you resize the graphical device and call the same plot.

plot(SurvHist,box2.col=2,box2.label="experienced\nR user")
#> Warning: The dimension of the boxes may depend on the current graphical device
#> in the sense that the layout and centering of text may change when you resize the graphical device and call the same plot.

plot(SurvHist,
     box2.col=2,
     box1.label="newby",
     box2.label="experienced\nR user",
     oneFitsAll=FALSE,
     arrow1.length=.5,
     arrow1.label="",
     arrow1.lwd=4)
#> Warning: The dimension of the boxes may depend on the current graphical device
#> in the sense that the layout and centering of text may change when you resize the graphical device and call the same plot.


## change the cex of all box labels:
plot(SurvHist,
     box2.col=2,
     box1.label="newby",
     box2.label="experienced\nR user",
     oneFitsAll=FALSE,
     arrow1.length=.5,
     arrow1.label="",
     arrow1.lwd=4,
     label.cex=1)
#> Warning: The dimension of the boxes may depend on the current graphical device
#> in the sense that the layout and centering of text may change when you resize the graphical device and call the same plot.


## change the cex of single box labels:
plot(SurvHist,
     box2.col=2,
     box1.label="newby",
     box2.label="experienced\nR user",
     oneFitsAll=FALSE,
     arrow1.length=.5,
     arrow1.label="",
     arrow1.lwd=4,
     label1.cex=1,
     label2.cex=2)
#> Warning: The dimension of the boxes may depend on the current graphical device
#> in the sense that the layout and centering of text may change when you resize the graphical device and call the same plot.



## The pbc data set from the survival package
library(survival)
data(pbc)
plot(with(pbc,Hist(time,status)),
