You somehow didn't "attach" the MASS package properly :
For me :

  > library(MASS)
  > find(max.col)
  [1] "package:MASS"

You write 
    library(<pkg>)
for every package <pkg> you want,
in the case of VR, one of
   MASS, spatial, nnet, class

{{and I *do* second  a proposition for allowing
  package(..) to be used synonymously to library(..) !!
