William, I had a problem similar to Wolfgang and I solved it through your help. Many thanks!
Just an observation which sounded strange to me ( I am not a statistician, just a wildlife biologist) I have noticed that running the pca using principal with raw data (and therefore using scores=TRUE in the command line) gives different pca scores than running the same pca with the correlation matrix (using scores=FALSE in the command line and therefore calculating the scores in the way you suggested to Wolfgang). Is that normal?
