Hello,
I have some problems with as.Date.
strDates <- c ("01/05/1965", "08/16/1975")
dates <- as.Date (strDates, "%m/%d%/%Y")
dates
[1] NA NA # I expected my dates. What was going wrong?
Thanks
Hermann

Hi,
Check for the additional "%" in your code "%d%".
?as.Date(strDates,"%m/%d/%Y")
#[1] "1965-01-05" "1975-08-16"
A.K.
