Alejo,
The default in gpagen() aligns the coordinates and then projects into Tangent
space. Thus they are Procrustes Tangent coordinates (see help file). One can
disable the projection step using the option Proj=FALSE.

Subject: geomorph gpagen coordinates
To: [email protected]
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
