date format

You need the day to convert to a date format. Assuming day=15:
x.date <- as.Date(paste(as.character(x),"-15",sep=""),format="%Y-%m-%d")

Hi,
I have a problem with a vector (x) containing dates in
format "yyyy-mm" (I'm working with monthly means): how
can I convert it in date format, so that I can plot it
recognising trends for my variables?
class(x) says: factor
Thanks
Alex

Small point but since:

- the paste function will convert its arguments to character
- as.Date will give you the format requested anyways 
- minus is the logical separator here

we could modify that to:

	as.Date(paste(d, 15, sep = "-"))
