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!
