Milos,
At present, bilat.symmetry() does not return the symmetric components for each specimen. That is something we could add in the next version. As for FA, one can assess this for a population using bilat.symmetry() (see the help file for instructions).

Subject: bilat.symmetry output in geomorph
To: "[email protected]" <[email protected]>
Hi to all morphometricians,
I was wondering how to use bilat.symmetry function from geomorph package in
order to extract symmetric and asymmetric components of shape variation in the
case of object symmetry.
By looking at the function code it can be observed that DA.mns and FA.mns arrays
are used for plotting shape changes associated with directional and fluctuating
asymmetry, but they only represent extreme configurations. Is it possible to
return landmark coordinate
arrays for every individual so that they can be used as the gpagen$coords
output, but separately for symmetric and asymmetric component of shape variation
(individual scores on symmetric and asymmetric component and their
coordinates)?
Also I am wondering is there a way to quantify FA per populations (or any
groups) using this package?
Best regards,
