Subject: Remove 100 years from a date object
Hello,
I have some data that has dates in the form 27.02.37. I convert them to
a date object as follows:
as.Date(data$date,format="%d.%m.%y")
But this gives me years such as 2037 when I would like them to be 1937.
I thought of trying to take off some time i.e.
as.Date(camCD$DoB,format="%d.%m.%y") - 100*365
But that doesn't seem to work out correctly. Any ideas how to do this?
Thanks
Dan
