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

If you have a named list and want to remove a specific element you can try:

lst <- list(a = 1:4, b = 4:8, c = 8:10)

if("b" %in% names(lst)) lst <- lst[ - which(names(lst) == "b")]

This will make a list lst with elements a, b, c. The second line removes element b after it checks that it exists (to avoid the problem @hjv mentioned).

or better:

lst$b <- NULL

This way it is not a problem to try to delete a non-existent element (e.g. lst$g <- NULL)
