Yes. I agree that plot is going to be crowded. But idea is to see if elements

I would need only first two principal components (at most three). Since
princomp calculates all components, it is taking very long time !

the square matrix as input. Which could be reconstructed(or you have it
already.) I do not know if there is a biglm() alternative to princomp(), but
maybe consider using subsets of your data because that plot, if crea
2 matches
