SAS Day 52
Once I use SAS proc import a Special Adverse Event dataset, everything looks good, except the variable name was directly from excel and has space and special characters like “/” (EOI/ Search)
Little Challenge: How to Rename a variable with space or special characters?
Basic Rename Syntax:
*1. within dataset data a; set a; rename old_name=new_name; run; *2. on the first line; data a(rename=old_name=new_name); set a; run;
Although this approach works majority of the time, it won’t work with the special characters or there are spaces in the variable name.
Advanced Rename Syntax with Special Characters:
data a; set a; rename "old name"n= new_name; run; *example; data sm; set sm; rename 'eoi/search strategy'n=eoi_search; rename 'MedDRA Code'n=medra; rename 'MedDRA PT'n=pt; run;
Output:
Happy Studying!
