gap.barplot: 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.

Value

The center positions of the bars.

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.
