I am reading in multiple files with the same file layout, except for a created variable in each load statement.
I want to be able to add (sum) each of the created variables, which provides me with a combination variable (combo).
For example, the variables are var1, var2, var3, etc. Var1=1, Var2=10 and Var3=100. I want a variable that is a combination of 111. Combo = 111 or Combo = 101.... you get the idea.
Help. So the question is:
Do I calculate a new variable?
Do I develop and expression?
Do I use the “aggr” function?
I am new at this so I might need detailed instructions. I have attached a brief PowerPoint description of the desired outcome.
Thanks in advance.
