Edgar,
If you perform a multivariate regression of shape on size (shape~size), the
residuals from this regression represent that shape component not explained by
size variation and the relationship between the two. In the literature, this is
commonly referred to as size-adjusted residuals or allometry free shape.

Subject: [MORPHMET] Question about size adjusted residuals in Geomorph
Hi everyone, I'm working in Geomorph package in R and I have a question
regarding working with allometric effect.
What is the difference between size-adjusted residuals and allometry free
shapes.
Thanks in advance
