[R-sig-eco] how to extract residuals from discriminant axes?

2012-09-06 Thread Chris Martin
Dear all, Is it possible to extract the residual variance not explained by two discriminant axes? Here is my setup: 1. I constructed a linear discriminant space based on 16 continuous traits measured for 3 species using the lda function from the MASS package (3 species ~ 16 traits). 3 categories
