If I understand your question, then you should just study some
examples/other people's code that initialize new objects as the return
values of functions. There are two small examples below. On the other
hand, if you really need a _global_ object, see help(assign).
## Example 1: last line is return value; this is a numeric
x <- function(y) {
y + 1
}
## now newvar contains the return value of x(3); you can
## pass this object as an arguement to other functions
newvar <- x(3)
## Example 2: return a list of values
xx <- function(y) {
return(list(z = y + 1, s = 100))
}
## can pull the list elements out of newvar later
newvar <- xx(3)
## e.g.,
z <- newvar$z
