I ran a PCA on my data and want to modify the score plot so that I can label each point according to a column value. This seems like a pretty obvious thing to want to do but I can't seem to figure out how to do it. Also, is there a straightforward way to access the plots directly rather than in the tiny window with all the PCA results? I'd appreciate any pointers for this obvious newbie, even just the right words to use to search for help.
