How can I remove an element from a list?

Question

I have a list and I want to remove a single element from it. How can I do this?

I\'ve tried looking up what I think the obvious names for this function would be in

Answer 1

I would like to add that if it's a named list you can simply use within.

l <- list(a = 1, b = 2)    
> within(l, rm(a))
$b
[1] 2

So you can overwrite the original list

l <- within(l, rm(a)) 

to remove element named a from list l.
