converting factor data frame to date data frame

Question

I have such a data frame(df) which is just a sample:

df<- as.data.frame(as.factor(
c("16.04.2015", "04.08.2014", "11.09.2013",  "20.11.2015", "04.04.2014")))

How can I change this data frame into date formatted data frame. I will be very glad for nay help. Thanks a lot.
