vectors or lists containing
numeric components (e.g., the output of split).
name
character vector of names for the groups.
Default is TRUE to put names on the x-axis. Such names are taken from the
data vectors or the names attribute of the first argument if it is a list.
Set name to FAL
main
main title for the plot.
xlab
x axis label.
ylab
y axis label.
srtx
rotation angle for x-axis labels. Default is zero.
Value
There are no returned values
Side Effects
A plot is created on the current graphics device.
BACKGROUND
Box-percentile plots are similiar to boxplots, except box-percentile plots
supply more information about the univariate distributions. At any height
the width of the irregular "box" is proportional to the percentile of that
height, up to the 50th percentile, and above the 50th percentile the width
is proportional to 100 minus the percentile. Thus, the width at any given
height is proportional to the percent of observations that are more
extreme in that direction. As in boxplots, the median, 25th and 75th
percentiles are marked with line segments across the box.
