Subject: column of dates into time series
i have a column of dates in this format:
data[,"Raised.Date"] <- as.Date(data[,"Raised.Date"], "%d/%m/%Y");
data[1:10,"Raised.Date"]
[1] "2006-07-07" "2006-07-07" "2006-04-03" "2006-04-03" "2006-04-03"
"2006-04-03" "2006-04-03" "2006-04-03" "2006-04-03" "2006-04-03"
I can turn them into months like this...
Month<-months(data[,"Raised.Date"])
Month[1:10]
[1] "July" "July" "April" "April" "April" "April" "April" "April" "April"
"April"
But i also want to turn them into years (and also weeks later on), so tried
this...
Year<-year(data[,"Raised.Date"])
Error: could not find function "year"
thanks.
