Generate random numbers from a multinomial.
?rmultinom
# The following will generate n multinomial vectors each of size m
rmultinom(n, size=m, prob=m^(-1/8)) # you need to specify probabilities
appropriately

Subject: [R] How to generate a correlation matrix with restrictions on its
eigenvalues
Dear All,
I would like to generate m positive real numbers c_i, I=1,...,m, such that
(1) c_1 + c_2 + ... + c_m=m,
(1) after being ordered into c_1 >= c_2 >= .... >=c_m>0, we have that c_m is
of the same order of m^(-1/8), when m is sufficiently large.
Thanks,
-Chee
