I don't disagree with the other answers, but I'd like to talk about what I
see as a more underlying issue.
Generally speaking, functions return the value of the last expression
within them.
myfun <- function(x) {
z <- sqrt(x)
2
}
Then
y <- myfun(7)
assigns 2 to y because 2 was the last expr
That's it ! Sorry for writing in a hurry, Merm!

Hi merm,
In case Sergio's message is a little cryptic:
return_a_list<-function() {
a<-"First item of list"
b<-c(2,4,6,8)
c<-matrix(1:9,nrow=3)
return(list(a,b,c))
}
x<-return_a_list()
x

Collect in a vector or dataframe or list the variables of interest and
output it.

Hi!
So I'm trying as the header suggests to assign the value(s) output by a
function to a variable, say 'y'
Problem is from what I gather any variables introduced within the function
are contained and the only output I can get is "return(value)" which is
awkward to work with. Any suggestions?
