Hello, Andreas
I'm glad the previous replies helped you solve your problem.
I think your original problem, though,
was caused by a typo. Note
the comma between the month and the year in your script and
the
period between the month and the year in Jim Holtman's
script.

>> y <- as.Date(x, format="%d.%m.%Y")
>> y

Hope this helps for the future
