Hello, I am sorry for asking such a basic question. I could not find an answer to it using google.
I have a discrete variable (a vector x) taking for example the following values : 0, 3, 4, 3, 15, 5, 6, 5 Is it possible to know how many different values (modalities) it takes ? Here it takes 6 different values but the length of the vector is 8. I would like to know if there is a way to get the set of the modalities {0,3,4,15,5,6} with the number of times each one is taken {1,2,1,1,2,1} Thank you very much P.S. : is there some useful functions for discrete variables ?
