model.matrix, the first p effects correspond to
coefficients and the remaining n-p ones to residuals.
Usage
effects(object, ...)
effects.lm(object, set.sign=FALSE)

Examples
y <- c(1:3,7,5)
x <- c(1:3,6:7)
( ee <- effects(lm(y ~ x)) )
c(round(ee - effects(lm(y+10 ~ I(x-3.8))),3))# just the first is different
