[R] Output args?

[Ben Bolker]

  You may want to look at the help for "assign", or, as a shortcut, try
the "<<-" version of assignment:

> foo <- function() { a <- 1 }
> foo()
> a
Error: Object "a" not found
> foo <- function() {  a <<- 1 }
> foo()
> a
[1] 1

  Note that this kind of question will eventually lead you into the thick
of issues like environments, scoping, closures, etc. ... but for simple
global assignment I think "<<-" is what you need.

> foo<-function(x,y,z){
>   ...
>   abc<-list(a=x,b=y,c=z)
> }
>

> 
> foo(1,2,3)
>
