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.
