The uniform distribution on the simplex
Generates random compositions with a uniform distribution on the (rcomp) simplex.
runif.acomp(n,D) runif.rcomp(n,D)
n |
number of datasets to be simulated |
D |
number of parts |
a generated random dataset of class "acomp" or "rcomp"
drawn from a uniform distribution on the simplex of D parts.
The only difference between both routines is the class of the dataset returned.
