[kjetil halvorsen]

 help.search("ginv")


gives the following:

Help files with alias or title matching `ginv',
type `help(FOO, package = PKG)' to inspect entry `FOO(PKG) TITLE':

ginv(MASS)              Generalized Inverse of a Matrix
ginv(multcomp)          Generalized Inverse of a Matrix

so you must say for instance
library(MASS)

and then
?ginv
