Hello, I try to define a global variable.
You should not do that unless you really know why you want it this way. You probably want to read the R Language Definition manual. Anyway, read ?assign if you want to proceed doing dangerous things. Uwe Ligges
My example:
R> a <- "old"
R> test <- function () { a <- "new" }
R> test()
R> a # shoud be "new"
This doesn't work. I would like to modify the variable "a" in a
procedure. How can I do that.
Thank you for helping.
