Description
Given the number of states, this function returns all of the
pairs of indexes corresponding to those states.
Usage
1
Rcpp_combn_zerostart(n_to_choose_from, k_to_choose, maxlim = 1e+07)
Arguments
n_to_choose_from
N in N choose K
k_to_choose
K in N choose K
maxlim
To avoid memory overruns, the number of combinations can be no larger than maxlim
(default: 1e+07)
Details
The C++ version is MUCH faster than the plain-R version.
Value
outarray an integer matrix with outarray rows; the number of columns is the
number of combinations.
