You can assign the environment within main to a variable in the global environment and that will make it accessible even after main terminates:
main <- function() { assign("main.env", environment(), .GlobalEnv) x <- 1; y <- 2 } main() main.env$x main.env$y # or attach(main.env) search() # note that main.env is on search path x y detach() # remove from path now that we are finished Alternately you could assign each variable within main that you want to save: main <- function() { x <- 1; y <- 2 assign("x", x, .GlobalEnv) assign("y", y, .GlobalEnv) } main() x y On 2/8/07, Geoffrey Zhu <[EMAIL PROTECTED]> wrote: > Hi all, > > When I write a script, I'd like to create a main() function so that I > only need to type main() t re-run it.
