I am using R version 2.0.0 (2004-10-04) on Fedora Core 2.
This works correctly:
> foo <- function(x=1,y=2) { c(x,y) }
> bar <- function(n,...) c(n,foo(...))
> bar(10,3)
[1] 10 3 2
But it goes wrong if I replace "c" in bar with "replicate":
> foo <- function(x=1,y=2) { c(x,y) }
> bar <- function(n,...) replicate(n,foo(...))
> bar(10,3)
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
[1,] 0 0 0 0 0 0 0 0 0 0
[2,] 2 2 2 2 2 2 2 2 2 2
It is mysterious why x was bound to the apparently arbitrary
value 0 while y was left at its default.
The ... arguments to bar seems to be ignored altogether.
bar(10), bar(10,x=3), and bar(10,3,4) give the same result.
Furthermore, bar(10,extra=3) does not give an error.
Perhaps this mysterious behavior is unavoidable because of
the kind of hack replicate is?
Thanks ...
