Hello,

 

I have a dataset that has lab draws over the span of a few days (example below). I want to create a dataset that has a unique line for each patient, with variables iterating _1, _2, etc. for each draw. I have tried to use an array, but am not very experienced with them so any help is much appreciated.

 

Thanks!

 

Dataset I currently have:

PatientALTASTINR
120241.01
133481.03
215301.11
217321.25
218331.30

 

 

Dataset I want to have:

Patientalt_1ast_1inr_1alt_2ast_2inr_2alt_3ast_3inr_3
120241.0133481.03...
215301.1117321.2518331.30

 

Thanks again!

Usually, turning a long data set to a wide data set is a poor choice, and harder to handle.

 

What analysis/table/report are you trying to create with this data?

I completely agree. I am just adjusting the data to fit into a historic database that was created long before I was working on it, so to fit it in I unfortunately need to make it wide.
