[R] defining a template for functions via do.call and substitute.

[john.gavin@ubs.com]

Hi,

Given a function

  fun <- function(a, b) a + b

how do I generate the function 'function(x, y) x + y'?

Working from the help files and Bill Venables' R-news article (June 2002),
I have tried various permutations with substitute without success. 
e.g.
  do.call("substitute", list(fun, list(a = as.name("x"), b = as.name("y"))))

Regards,

John.
