Hi Pablo, As already mentioned, there is the function interlmkdist in geomorph ( https://www.rdocumentation.org/packages/geomorph/versions/4.0.3/topics/interlmkdist), which calculates the distance between landmarks according to your given scale (mm, cm, etc). However, I believe it calculates the distances between landmarks before Procrustes.
