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
