converting a POSIX class variable to a date class is easy. dates<-as.Date(x) #where X is of class POSIX How does one do that to all columns in a data frame that are of POSIX class and leave all the other columns (integers, factors) as is.
Feel free to reply with just one or two buzzwords that I could then search for to find how to do it.
