[R] [PS] discrete variable

Try table(), with the name of your vector inside the parentheses.

Subject: [PS] [R] discrete variable

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 ?
