At least as.Date() works for me for *one* of your factor labels:
as.Date(factor("01.02.2006"), "%d.%m.%Y")
[1] "2006-02-01"
So, please read the posting guide before posting and learn that you
should tell us:
What is the error message? Which R version is this? What are all the
labels (in order to reproduce your error)?
in order to get better help.
