Re: [R] Generate random vectors (continuous number) with a fixed sum

If a uniform sample is needed, it's fairly easy to turn my solution into a rejection sampler that is uniform across the region satisfying the constraints. It has an acceptance rate that is bounded below by something like 1/factorial(dim-1), e.g. 1/6 in 4 dimensions. Duncan Murdoch On 2025-04-

In '?rep' find out about the 'each' argument. Also there is the function 'gl' which creates a factor and offers a shorter syntax for your problem. If n equals 5 use one of: rep(seq(5), each = 4) gl(5,4) On 19 April 2015 at 15:44, John Sorkin wrote: > Windows 7 64-bit > R 3.1.3 > RStudio 0.98.1
