[R] New R on Mac user fails to run MASS

[Michael Kubovy]

My R installation (Mac OS9.2.2) is working, but when I try to run the
examples from Venables & Ripley (p. 6):

R : Copyright 2001, The R Development Core Team
Version 1.4.0  (2001-12-19)

...

> library(MASS)
> x<-rnorm(1000)
> y<-rnorm(1000)
> truehist(c(x,y+3),nbins=25)					% Plots nicely
> dd<-con2tr(kde2d(x,y))						% Doesn't complain
> contourplot(z ~ x + y, data=dd,aspect=1)
Error: couldn't find function "contourplot"
> wireframe(z ~ x + y, data=dd,drape=T)
Error: couldn't find function "wireframe"
