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,
