[R] right assignment ("->") and functions

[Robin Hankin]

Hi again list.

Thanks for these replies.  I guess the issue is one of parsing units
being different from my expectations.  I saw a related issue in a
slightly different context a couple of days ago:


R> f1 <- function(a,b)
{a
-b}
R> f2 <- function(a,b)
{a-
 b}


...which (rightly) give very different results [the original bug took
me *hours* to find].

cheers
