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 the reference manual and I haven't found anything appropriate. Select the correct answer from above options

You can remove a particular element from a list as follows: Mylist[[i]] <- NULL This will remove the ith element from the list, where i is the index of that element. Note: This method shuffles the index of elements after removing the element. If you don’t want to modify the list, you can use negative indexing to not include a particular element. For example: x <- list("A", "B", "C", "D", "E") x[-2] x Output 1: [[1]] [1] "A" [[2]] [1] "C" [[3]] [1] "D" [[4]] [1] "E" Output 2: [[1]] [1] "A" [[2]] [1] "B" [[3]] [1] "C" [[4]] [1] "D" [[5]] [1] "E"
