Hi all, I want to plot the outcome of my PCA analysis (done with prcomp()), but I have so many variables that plotting them obscures the whole plot. How do I suppress the plotting of variables in a biplot? I only want to see the units. I appreciate both data constitute a biplot, so alternatively what do I need to extract from the prcomp object in order to only plot the data I want? I've tried $x from the objects which gives the right relationships between the data, but the not the same values as in a biplot. Anyone able to give me some pointers, please?
