I am trying to understand why R is working in a particular way. I have a
data set with two variables; mark date (markd) and recap date (recapd). I
would like to know the number of days between capture dates. But if I
subtract recap date from mark date I often get the wrong results.
Well, what are the classes of recapd and markd in your case?
