Alan--
You could roll your own, by writing a wrapper for each regression
command that parses expressions, generates tempvars, and labels them
with the relevant expression. Don't users of R have to program their
own stuff every time?

Hi - I have been demonstrating the wonders of Stata to users of R and
have been embarrassed by their criticism of Stata's inability to
transform a variable within the syntax of a command. For example reg y
log(x) won't work. The variable z=log(x) must be generated first. I'm
curious as to whether other statistical software besides R allows this
sort of thing. At any rate, I would strongly urge Stata Corp. to
incorporate this sort flexibility.
