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).

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?
