[Rd] Context problem with ... and rbind (PR#860)

[ripley@stats.ox.ac.uk]

R 1.2.2, Solaris and Linux:

f <- function(x, ...)
{
   g <- function(x, ...) x
   rbind(numeric(), g(x, ...))
}
> f(1:3)
Error in rbind(numeric(), g(x, ...)) : ... used in an incorrect context

S-PLUS 3.4 gives

     [,1] [,2] [,3]
[1,]    1    2    3

as I would expect.

f <- function(x, ...)
{
   g <- function(x, ...) x
   tmp <- g(x, ...)
   rbind(numeric(), tmp)
}
> f(1:3)

does work, and I believe this should be equivalent.


This is an abstract of code used in the latest S version of the boot
package.
