Let's says I have this code:
is.numeric(mean(mtcars$mpg))
Let's says I highlight the code and press CMD+E to use code as find. What regular expression can I use to strip the outer function? So the replacement code would be mean(mtcars$mpg)
Cheers Ross

I think this questions is underspecified. What exactly are your requirements for how the functions look? What is your goal here (e.g. to run a global search and replace on a specific function call wrapped by an arbitrary other function call and strip the other)?
Perhaps the whole question didn't get posted
I would select is.numeric(mean(mtcars$mpg)), hit use as find, and use a regular expression to replace is.numeric(mean(mtcars$mpg)) with mean(mtcars$mpg).
In another instance, I would select is.character(length('a', 'b')), hit use as find, and use a regular expression to replace is.character(length('a', 'b')) with length('a', 'b').
In another instance, I would select summary(lm(y ~ x)), hit use as find, and use a regular expression to replace summary(lm(y ~ x)) with lm(y ~ x).

Assuming the outer function name is only word characters and inner function is word characters or the dollar sign, you can search for: \w+(([\w$]+(.*?)))
Then replace with $1 (capture register one).
I would recommend that you study regular expressions and also TextMate’s format strings, for the more TextMate specific stuff, here are some useful links:
