Hello Group,
I'm trying to learn R and am having a problem getting output from a
function I'm trying to write. The problem is clearly one of scope,
but I can't find the documentation that tells me how to get around the
issue.
Here is an example of my problem.
testfunc<-function(x)
{ y<-10
print(y)
print(x)
}
testfunc(4)
The variables x and y are accessible during execution of the function
"testfunc" but not afterwards. I've read through the Introduction to
R, and the R language definition on functions, but do not see how to
define the output of the function, or change the scope of a function
variable using the R equivalent of a %global statement as would be
done in SAS. Can someone tell me either where I can look for more
information or how to make x and y accessible to operations after the
function is run?
Thanks in advance for any suggestions.
