Hi all,
>From many time ago, I have return to R, I have a matrix with this values. C(jose, pepe, jose, luis, pepe, raul) I want to "read" this matrix or element and extract all different values, so the output matrix (that I want to download is: c(jose, pepe, luis, raul). There is a function to do this? Many thanks in advance.
