Hi, I have a list:
tmp0 <- list(a=1, b=2, c=3) And I realize that I can append a NULL element to the end of this list, just by writing: length(tmp0) <- 4 Now, the question is, how can I assign NULL to one of the existing list elements without changing the length of the list? Please note I am working from inside a for loop that is working on one list element at a time and in some circumstances I want to set one element to NULL. So, specifying the whole list again as in: tmp0 <- list(a=1,b=NULL,c=3) is not an option. But writing, say: tmp0 [[2]] <- NULL is not an option either, because it leaves me with a list of length 2. Is there a solution for this?
