There is some question of what should be returned if its Feb 29th and
in 6 years Feb only has 28 days; however, that aside
try this which does not involve any internals and works for both Date
and chron dates:
> y6 <- function(x) {
+ for(i in seq_along(x)) x[i] <- tail(seq(x[i], len = 7, by = "yea
I have a character vector of dates, comme ci:
> irving
[1] "12/05/1987" "11/07/1986" "08/29/1987" "01/26/1988" "06/21/1988"
[6] "03/17/1987" "02/24/1988" "10/04/1986" "03/19/1987" "01/02/1987"
For reasons best known to myself ( ;-) ) I want to add six years to the
year in each of these dates
