outliers in boxplot

Fri, May 12, 2000 8:37 AM

Hi All,

I'm trying to draw a number of sidee-by-side boxplots with quite a
large number of outliers.  The default in R is to plot these using
the current value of par("pch").  I would like to plot them as
horizontal lines of length k times the width of the boxes.  Essentially
what I want is the equivalent of the S-Plus parameters
outline=T, outwex=k
which do not seem to exist in the R version of boxplot.

Also the helpfile for boxplot says that graphical parameters can be
passed but the pch parameter is ignored if supplied. Is this
intentional?

Thanks in advance,
