Hi everybody. I have a dataframe that contains a factor with the date
information in the format like in the example below:
"2009/05/12 11:22:31 AM"

I have been able to convert it to POSIXt using strptime

Now I want to print only the date as one vector and the time in another
vector but they must be real date and time classes so that i can use them in
calculations

to reconstruct my situation:

date=as.factor("2009/05/12 11:22:31 AM")
posix.date=strptime(date, "%Y/%m/%d %I:%M:%S %p")

I tried:

time=format(posix.date, "%A %H:%M") # For weekday, hour and minute

but the class in character. Now it prints like i want but it cannot be used
in calculations.

I would appreciate any suggestions

Thanks in advance
Christiaan
