Tim,
You might also make sure you have the very latest version of geomorph from CRAN
(version 2.1.2). In the previous version with PrinAxes the ‘flipping’ sometimes
occurred. That should be resolved in vsn 2.1.2.

Subject: [MORPHMET] Re: gpagen in geomorph flipping axes?
Thanks everyone for the helpful insight!
Turns out that by including "PrinAxes=False" in the gpagen command the original
orientation of the specimen is maintained (thanks to the ever helpful Emma
Sherratt for pointing this out!)

Hello all,
Does anyone have any experience with 2D landmarks in the geomorph package? When
using the gpagen function my specimens are projected at different rotations
depending on some unknown factor. Can anyone help?
