remove multiple elements from vector
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. HTH, baptiste

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? Thanks.
