Chars as numbers

Is there a proper function for transforming
a character to a number instead of using

  i=match('c',letters)
  # 3

I'd suggest to use the above if you really mean it. Note that 
"transforming a character to a number" is not well defined, because you 
have to think about encodings and characters at first. See the article 
by Brian Ripley in the most recent issue of R News, for example.
