R help - Feb 2014 - Geomorph package: gpagen coordinates in tangent space?

Hi all, first thanks for a so useful package! I have a question about
"gpagen". I understand that the resulting coordinates of this command
are
in shape space, so for statistical analisys one must project them to
tangent space. But the command "plotTangetSpace" runs
"prcomp" directly
over gpagen's coordinates. The gpagen's resulting coordinates are
already
on tangent space? Thanks a lot in advance

Alejo
