Hello, I would like to take a data set of doctors, and recategorize them into numbers. For example, John Doe would be assigned as 1 Jane Doe would be assigned as 2 Does anyone know how to do this in R? It seems quite easy, yet I cannot find the code.

Unless you have good reason and know what you're doing, **don't do this!** It is just asking for trouble. ... and yes, it is easy. Have you gone through the "Intro to R" tutorial that I believe would provide you the information to do this?
