Brad,

FYI, I modified i.pca awhile back to write eigenvectors to all output

This is great, thanks a lot.

Could you give a hint as to the direction of the matrix, i.e. what's in the rows and what's in the columns ? How difficult would it be to add row names and column headers to make this obvious ?

I think that i.pca should have a flag to outout this info directly to stdout, and not only to the history. IMHO, the eigenvectors are pretty important for the interpretation of the pca results.
