Hi,

The princomp() function has a nice method to generate a pretty biplot of
the data.  I have some data where the points are divided into a few
groups.  My intention is to generate a biplot, using princomp, but color
the points based on group membership.  The hope is that points will show
some kind of clustering by group in the biplot.

However, I can't figure out how to indicate individual point color in a
biplot.  The only setting I found was to indicate a single color for
*all* the points.

Any ideas?
