Hello,
Try the following.
x <- c("14.Aug.2012-16:32", "3.Sep.2012-16:50")
y <- c("2012.08.14", "2012.09.3")
as.Date(x, format = "%d.%b.%Y-%H:%M") == as.Date(y, format = "%Y.%m.%d")
(Or use %in% instead of ==)
But note that the format returned by as.Date uses '-' as separator:
as.Date(x, format = "%d.%b.%Y-%H:%M")
[1] "2012-08-14" "2012-09-03"
Hope this helps,
Rui Barradas

Hi,
I have two data-frames which I want to match by a date-variable.
The problem now is, that the date-variable has a different format in this two
data-frames.
So simply matching by this variable wouldn't work.
In the one data-frame the date-variable contains strings that look like this:
14.Aug.2012-16:32
3.Sep.2012-16:50
etc.
in the other data-frame the date-variable looks like this:
2012.08.14
2012.09.3
is there an easy way to compare these two vectors?
Or is there an easy way to transform
14.Aug.2012-16:32
into
2012.08.14 ?
thanks!
