Box-percentile plots

DESCRIPTION:

Producess side-by-side box-percentile plots from several vectors or a list of vectors.

USAGE:

bpplot(..., name=TRUE, main="Box-Percentile Plot", 
       xlab="", ylab="", srtx=0)

ARGUMENTS:

...
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 FALSE to suppress names. If a character vector is supplied the names in the vector are used to label the groups.
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

set.seed(1)
x1 <- rnorm(500)
x2 <- runif(500, -2, 2)
x3 <- abs(rnorm(500))-2
bpplot(x1, x2, x3)
g <- sample(1:2, 500, replace=TRUE)
bpplot(split(x2, g), name=c('Group 1','Group 2'))
rm(x1,x2,x3,g)
