  Or you can be lisp-ish and use hyphens (or many other symbols) by quoting:

  > "scale-colour"=2
  > ls()
  [1] "scale-colour"

  but that requires further perversions:

  > get("scale-colour")
  [1] 2

  I like (3), aka camelCase - aka about a dozen other names: 
http://en.wikipedia.org/wiki/Camel_case - but that's mainly because its 
widely used in Python, and Python syntax is just marvellous. The more R 
syntax tends to Python syntax the better. Let's get rid of curly 
brackets and make whitespace significant...

  But I digress. As usual.
