I have a data frame (hf) that is all set up and the dates are working
fine - however I need to extract the months and hours (2 separate
columns) as numbers - however they are coming out as characters.
I have tried both the following:
hf50$hour= hf50$date
hf50$hour=format(hf50["hour"],"%H")
and
hf$month <- as.POSIXct(strptime(hf$date, format = "%m"))
but they are still coming out as characters.
Any ideas please?
Thanks,
Tim.
