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?
