?ginv provides 'Modern Applied Statistics with S' (MASS), 3rd, by Venables and Ripley as the sole reference. I happen to have this book (4th ed) on loan from our library, and as far as I can see, ginv is mentioned there twice, and it is *used*, not *explained* in any way. (It is used on p. 148 in the 4th edition.)
ginv does not appear in the index of MASS. ginv is an implementation of the Moore-Penrose generalized inverse, but I can't find any reference to an appropriate publication from Moore and Penrose in MASS either. Admittedly, MASS is inadequate as a reference for ginv, and it is desirable that the reference be corrected. Is this an isolated incident, or a general practice? (Perhaps the appropriate reference has been removed in MASS 4th?) vQ ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
