Hello everybody!

I have a question. I am working with R and I am loading a .txt from my
computer. This file contains a set of features from patients with numerical
values and the score, that determines the gravity of the disease( from 0 to
3). Due to I want to obtain a classification of my patients using
SVM,neural networks or C.4.5, I think I need to "convert" the numeric class
to nominal class, not?
I have thought to make a easy modification. The score is from 0 to 3. So, I
have converted "0" to nominal class "g0", and successively. But I am not
sure if this is the correct way to do it. Any information is welcome.

Thanks!
