proj.lm(object, onedf, unweighted.scale = F)

object:

an object of class lm, or inheriting from lm

onedf:

see lm

unweighted.scale:

Whether results are returned on the unweighted scale (useful for comparing results with the original response) or the weighted scale (which is the scale used for the data analysis). This only affects models with weights.

This is a method for the function proj for objects inheriting from class lm. See proj or proj.default for the general behavior of this function.
