subtract a time period from a date
Hello,
I don't get it, this seems to work as expected.
d <- as.Date("2011-05-01 CEST")
d - 30
[1] "2011-04-01"
Hope this helps,

Hello everybody, how can I reduce e.g. 30 days from a date? When I do the following "2011-05-01 CEST" -"2011-04-01 CEST" I get: "Time difference of 30 days" an thats fine. But when I try "2011-05-01 CEST" - 30 I get nonsense. So how can I subtract some days, month or years from a date? thanking you in anticipation Claudia Paladini
