R help - Sep 2001 - Request for Help: Rotation of PCA Solution or Eigenvectors

Dear R Helper,

I am writing because I seek to perform a varimax rotation
on my Principal Components Analysis (PCA)  solution. (I have been
performing PCA's using the eigen command in R.) If you can tell me
how to perform this rotation when I use the eigen command (or the
princomp command) I would be thrilled.

Thanks so much!

You must have the mva package if you are doing principle
components.  Look at the help for it.  You will see "varimax" as
one of the topics, and "factanal" as another.  I think that is
what is available.  I don't think you can do varimax rotation on
principal components (unless you write it yourself, assuming that
it is meaningful).
