There have been a few solutions already but I thought I would add one
that uses chron:
> library(chron)
> attach(month.day.year(chron(unclass(as.Date("2005-09-01")))))
> year
[1] 2005
> month
[1] 9
> day
[1] 1
or perhaps cleaner:
library(chron)
with(month.day.year(chron(unclass(as.Date("2006-09-01")))), {
... computations involving variables month, day and year ...
}
See R News 4/1 help desk article for info on dates. Particularly the table
at the end.
