np_multiset {iterpc} | R Documentation |
Calculate the number of r-permutations of a multiset
np_multiset(f, r, bigz = FALSE)
f |
the frequencies of the mutliset |
r |
the number of object drawn from the multiset |
bigz |
use gmp's Big Interger |
the number of r-permutations (Big Integer from gmp)
x = c("a","a","b")
# possible permutations of size 2 are "aa", "ab" and "ba".
np_multiset(table(x), 2) # = 3
