Hello,
Works with me:
x <- scan(what = "character", text = "14/12/2000 15/12/2000 18/12/2000
19/12/2000 20/12/2000 21/12/2000
22/12/2000 25/12/2000 26/12/2000 27/12/2000 28/12/2000 29/12/2000
01/01/2001 02/01/2001 03/01/2001 04/01/2001 05/01/2001 08/01/2001
09/01/2001 10/01/2001 11/01/2001 12/01/2001 15/01/2001 16/01/2001
17/01/2001 18/01/2001 19/01/2001 22/01/2001 23/01/2001 24/01/2001
25/01/2001 26/01/2001 29/01/2001 30/01/2001 31/01/2001 01/02/2001
02/02/2001 05/02/2001 06/02/2001 07/02/2001 08/02/2001 09/02/2001
12/02/2001 13/02/2001 14/02/2001 15/02/2001 16/02/2001 19/02/2001
20/02/2001 21/02/2001")
as.Date(x, format = "%d/%m/%Y")
You've posted the error message but not the command. If it is what it
seems to be, by looking at the error message, then you've passed the
wrong format argument. There is NO month 14 (first date of all!)
Hope this helps,
