Labeling points on plot on relative warp scores?

Hi there,

I am plotting relative warp scores (equivalent to pca scores) and I want to
label (color code and shape) the points by group. I can't figure out how to
do this beyond simple plotting. 

plot(RW1, RW2);

Do I need to make vectors of each group and then plot them separately onto
the same plot? How do I go about this?

Thanks!

Specify corresponding vectors for the argument "cex" and "pch".

Hi stephalope,
I've done this with "boxed.labels" in the plotrix package for factor 
analyses or PCAs when there aren't many variables. I use strong 
background colors for the box and white text for the variable names. You 
may have to shift some labels apart if they overlap, but it gives an 
easy to understand illustration of simple factor structures or PCAs.
