Subject: [R] returning multiple values
I am running a program which has an output containing four vectors named
meanfevs, meanfevns, pfevs, pfevns. I wish to return all four and be able
to access them later. I used the command
return(list(a=meanfevs,b=meanfevns,c=pfevs,
Indeed. You do not understand lists. The behavior you expect is not how R
works. Have you read "An Introduction to R" where this is explained
(section 6.1). Also chapter 10 and 10.7 in particular for scoping in R.

Hi,
No, you won't be able to simply call "a" and have that work.
R returns these in a single object with components (elements) named a,b,c,d
Here's a concrete example:
func <- function(x, y) return(list(a = x+1, b = y + 2))
out <- func(3, 5)
out[["a"]] # or out$a
out[["b"]] # or out$b
give

it did give me the ouput. However the values did not get
