Re: [R] Summary: do.call and environments

[Spencer Graves]

ff1 <- function(fun, x) {
 assign(fun, get(fun), 1)
 assign("x", x, 1)
 do.call(fun, list(y=3))
}
tst <- ff1("fx", 2)
     This assigns "6" to "tst" in both S-Plus 6.2 as R 1.8.1.  However, 
it also prints "[1] 6" in S-Plus 6.2 but not R.  ???

     I would have naively expected 14.  From whence cometh "6"?
     Also, I prefer to use transportable code wherever feasible.  The 


2*3=6, which was the intention. It is in fact only a proof of 
correctness, that "7" is not used here. The proposal of Gabor does 
exactly, what I want, but if it does not work on S-PLUS, it's a 
serious disadvantage and I should check this too.
