Hello,
I find out which package disturbs as.Date(). It is the package Epi:
> as.Date(36525, origin="1900-01-01")
[1] "2000-01-02"
> library(Epi)
> as.Date(36525, origin="1900-01-01")
[1] "2070-01-01"
> detach("package:Epi")
> as.Date(36525, origin="1900-01-01")
[1] "2000-01-02"
@Philipp: I assume that Epi will have the same affect on Linux. Maybe you have
the same library or another which conflicts with as.Date().

Thanks for the reply.
The original test was without the quote. The quote come into play when I try to
solve this problem changing from " to '. However, after restarting my PC the
as.Date(36525, origin="1900-01-01")
gaves me the correct output
[1] "2000-01-02"
After loading several libraries I got
[1] "2070-01-01"
I assume there is a conflict with a package. I will try to find the one and let
you know.

Or perhaps it is a problem with the OS services on the unstated R platform used
(this will use strptime from the OS). The single quote is definitely wrong,
however.
