[R] Aliases for arguments in a function

Hi all.

I have a function that I would like to use either the argument name as originally defined or another name. Within the function (and other functions) use the argument name as originally written, so I don't want to simply remove the old argument name for the new one, but simply allow the function to treat both argument names as equivalent.

Here is an example:

foo <- function(arg1, this)
if(this < 0) stop("this must be positive") return(arg1/this)

foo(arg1=5, this=10)

But, I also want foo() to work equivalently with the following (where 'this' and 'that 'are treated as if they were the same): foo(arg1=5, that=10)

Any thoughts would be appreciated.
