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.
Example: Dataset - markd recapd
8/28/1991
12/24/1994
Timeoutd<-recapd-markd
Timeoutd = 1945
But the number of days between should be around 1214.
Why is this happening and how do you fix it.
Thank you for all the help.
