[R] Histogram for factors

[Thomas Vogels]

Hi,

I keep running into this:
R> hist (f)
Error in hist.default(f) : `x' must be numeric

To which of course something like (simplified but not beyond repair):
R> hist.factor <- function (ff) {
  jj <- table (ff)
  jb <- barplot (jj, ylab="Frequency", xlab=deparse(substitute(ff)))
  axis (1, jb, names (jj))
}
R> hist (f)
is a possible solution.

Why is a 'hist.factor' not part of the base distribution?  Is this
kind of thing discouraged?  Usually not needed?  Am I missing sth else?

Thanks,
  -tom
