Hi all, what does the option singular.ok in funtion lm() means? I took a look in the help page of lm() and found: singular.ok logical, defaulting to TRUE. FALSE is not yet implemented.
Right. In S, it defaults to F, and means that lm refuses to fit a reduced-rank model. R always will (and have NA components in the coefficients).
