n_1 + ... + n_N = 2(N-1) is requested for integers n_i >= 1.
What about c(rep(2, N-2), 1, 1))?
but I'm afraid that this was not what you really wanted. ;-)
However, you didn't say if your sample should be random. :-)

Dear All,
I cannot unfortunately provide any R code, otherwise I would not need to
post this in the first place.
I need to generate a sample of N positive non-zero integers such that
their mean is *exactly* 2(N-1)/N, i.e. the mean depends on the length of
the sample.
For a start, we can assume that every integer in my sample can assume
only the values 1, 2 and 3.
Any suggestion is appreciated.
Cheers
Lorenzo
