dplyr::lag() seems to work fine, but dplyr::lead() seems not to.work. Am I doing something wrong, or is this a bug? Running R 3.6.1, dplyr version 0.8.3 on uptodate Windows 10.
Thanks for the help. Larry Hunsicker
> junk <- data.frame(thing = 1:5)
> junk %<>% mutate(last = lag(thing, 1))
> junk
thing last
1 1 NA
2 2 1
3 3 2
4 4 3
5 5 4
> junk %<>% mutate(next = lead(thing,1))
Error: unexpected '=' in "junk %<>% mutate(next ="
