Thanks for the messages. What I probably should have explained is that I have a
data.frame "file" with variables named "A", "B",
etc.. I wanted to use paste () to pull the names "file$A",
"file$B", etc. and stick them in table() and so get an output of
table(file$A). For the record, someone read my thinking and sent the following
solution which works well:
table(eval(parse(text=risk.factors[1])))
Thanks again. David.

As another poster said, you didn't actually tell us what you wanted. But
I wouldn't be at all surprised if ?get is just what you're looking for.
