Is this what you want?:
> li <- list(a=1, b=2, c=3, d=4)
> li
$a
[1] 1
$b
[1] 2
$c
[1] 3
$d
[1] 4
> unlist(li)
a b c d
1 2 3 4
> unname(unlist(li))
[1] 1 2 3 4

Subject: [R] Some kind of inverse of "names"
I wonder if there exists some kind of inverse of the "names" primitive in R. Let me explain what do I mean:
If I create a list:
-> li <- list(a=1, b=2, c=3, d=4)
then I can have:
-> names(li)
[1] "a" "b" "c" "d"
which is, I guess, some kind of vector, since
-> typeof(names(li))
[1] "character"
however, I haven't seen something that allows me to get the other side, i.e., the values.
Something like:
->VALUES(li)
[1] 1 2 3 4
Do you have any comments on this?
Thanks,
- Sergio.
