gap.barplot: Display a barplot with a gap (missing range) on one axis

In plotrix: Various Plotting Functions

Display a barplot with a gap (missing range) on one axis

Description

Displays a barplot with a missing range.

Usage

 gap.barplot(y,gap,xaxlab,xtics,yaxlab,ytics,xlim=NA,ylim=NA,xlab=NULL,
  ylab=NULL,horiz=FALSE,col,...)

Arguments

y	a vector of data values
gap	the range of values to be left out
xaxlab	labels for the x axis ticks
xtics	position of the x axis ticks
yaxlab	labels for the y axis ticks
ytics	position of the y axis ticks
xlim	Optional x limits for the plot
ylim	optional y limits for the plot
xlab	label for the x axis
ylab	label for the y axis
horiz	whether to have vertical or horizontal bars
col	color(s) in which to plot the values
...	arguments passed to ‘⁠barplot⁠’.

Details

Displays a barplot omitting a range of values on the X or Y axis. Typically used when there is a relatively large gap in the range of values represented as bar heights. See axis.break for a brief discussion of plotting on discontinuous coordinates.

If the user does not ask for specific y limits, the function will calculate limits based on the range of the data values. If passing specific limits, remember to subtract the gap from the upper limit.

Value

The center positions of the bars.

  ylab="Group values",main="Barplot with gap")
 gap.barplot(twogrp,gap=c(8,16),xlab="Index",ytics=c(3,6,17,20),
  ylab="Group values",horiz=TRUE,main="Horizontal barplot with gap")
