Hello everybody,

How could I extract the components of of a PCA to plot it into a biplot?
I want to make pairwise biplots of the first three main components:

biplot(princomp(x, cor=TRUE))
biplot(princomp(x[,c(1,2)], cor=TRUE))
biplot(princomp(x[,c(1,3)], cor=TRUE))
biplot(princomp(x[,c(2,3)], cor=TRUE))

Is this the only way, how I could plot them?
I thought, that it could be possible to extract them of the full PCA ..

KR,
Alin
