Hi, ?unique should work fine for this.
I think the problem in your implementation is that you modify x in the loop, in particular its length may become shorter than the stopping condition.

Hello all, one brief question I would like to remove double/triple elements from a vector, e.g. 0 1 1 1 1 2 2 2 4 5 6 6 but keep one of these multiple ones. Should look like this finally: 0 1 2 4 5 6 My function does not work somehow for(i in 2 : length(x)) { if(x[i]==x[i-1]) x <- x[-(i-1)] } any suggestion?
