Hi all, I realized what I was doing wrong and aplogize about posting before thinkg about it for long enough. If I try to plot the pca results directly (bulbil.pca), I can't do it. But if I extract the axes 1 and 2 and plot directly, I can add col=as.numeric(group.bulbil[,3]) to the text() function and it works the way I want it to work.
