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.
Thanks,
Ken
