[R] biplot

[Thomas W Blackwell]

Due to a name conflict with the other arguments to biplot()
named "xlabs" and "ylabs", you have to set those arguments
explicitly, in order to be able to set xlab="", ylab="" as
well.  The following command works for me:

biplot(princomp(USArrests), xlabs=dimnames(USArrests)[[1]],
  ylabs=dimnames(USArrests)[[2]], xlab="", ylab="")

This complication is unfortunate, but it's a consequence of
partial matching of argument names.
