pca function automatically mean-centers

It looks as if the pca function automatically mean-centers the data. Is this the case and if so how can I override this? I want to center my data using the median or group means.
Thanks Marì

You are right, by default PCA centers the data. You can however ask PCA not to do that:
Set the name value pair, 'Centered' to false.
