Hi, guys
I don't understand why I can apply as.Date to a single item in the list:
> as.Date(alldays[4])
[1] "29-03-20"
but when I try to lapply as.Date to all the items, i got a sequence of neg
numbers:
> sapply(alldays[1:4], FUN=as.Date)
03-04-2012 02-04-2012 30-03-2012 29-03-2012
-718323 -718688 -708492 -708857
does anyone know what's wrong here?
i am very confused!
Thanks a lot for your time in such a freezing weekend!
