Hi Keith,
A more specific example of what you're looking for might be
helpful--ie do you want to read global variables or set them? You
probably want to look at environments and closures; ?"<<-" and ?assign
are good starting points (the latter has an example of "Global
Assignment within a function")
The following code is what I think you're interested in:
> x <- 5
> ex <- function(k) {
+ x <<- x + k
+ 2^x
+ }
> x
[1] 5
> ex(1)
[1] 64
> x
[1] 6
Best,
Gray
