How to format dates (with no century)?
Hi,
I have dates in this kind of format (day, month, year):
> dput(head(dates, 10))
c("6.4.7", "29.12.98", "19.10.91", "20.6.92", "2.9.3", "23.6.3",
"13.7.93", "23.3.7", "26.6.95", "15.2.10")
So, as you can see, there is no century. How can I change this
character data into dates? Any help
