Hi,
I am using Stata 9, and I have data for patients who came to the
clinic on seperate occasions.
I am trying to create new variable, called "visit" and to mark the
"visit number" per patient.
For example:
Patient 1, came on Jan,1, 2007, Feb.1, 2007, March 1, 2007 etc..
How to code "visit" variable to have "1" for Jan.1
"2" for Feb1
"3" for March 1?
etc..
Thank you & best regards from South Africa
