[Rd] Creating vignette pdf on Windows

[Gabor Grothendieck]

On page 11 of the Extensions manual it says that "R CMD build will
automatically create PDF versions of the vignettes for distribution"
however, I have not been successful on Windows 2.0.1 beta.

I tried creating a simple package by entering the code in
the ?package.skeleton example then adding the Rnw file from
the utils package to AnExample\inst\doc but when I ran 
  R CMD build 
it did not seem to create a tex or pdf file.  What am I
doing wrong?


... In R
R>          f <- function(x,y) x+y
R>          g <- function(x,y) x-y
R>          d <- data.frame(a=1,b=2)
R>          e <- rnorm(1000)
R>          package.skeleton(list=c("f","g","d","e"), name="AnExample")
