Hi all,
I have one data set in which there is total number of case of a disease by date. The date is in Month, Year e.g Jan 2015, Feb 2015, Jan 2016 format. I want to categorize the number of cases by date e.g. before Jan 1915 and after Jan 1915. I could not perform function like if date<Jan 1915 as I would do with the numeric data.
Please help.
Thanks!
You specify a SAS date literal as 'ddMonyy'd
For example:
'01Jan1915'd
It works !! Thank you very much for the quick reply.
