How to rename element's list indexed by a loop in R

Question

I\'m new on R language and I still have a lot to learn. I\'ve a list W of J elements and I would like to rename its elements W[[i]] with Wi

Answer 1

names(W) <- paste0("W", seq_along(W))

should do the trick.

Note that paste0 was introduced in R 2.15 as a "slightly more efficient" version of paste(..., sep = "", collapse) . If you are using an earlier version of R, you can achieve the same using paste:

names(W) <- paste("W", seq_along(W), sep = "")
