Only the source code.
"coefficients", "fitted.values", "residuals", "terms", "call",
"xlevels" and "model" are as in lm, and "scale" is the estimate
of the scale of the residuals.

crit is the best value found of the fit criterion, "sing" is a message
about singular fits found, and "bestone" is numbers of the points used for
the best fit.

No.
