Description
Get the next permutation(s)/combination(s) for a iterator
Usage
getnext(I, d = 1, drop = TRUE)
Arguments
I
a permutation/combination iterator
d
number of permutation(s)/combination(s) wanted, default to 1
drop
if d is 1, drop simplify to vector if possible, default to TRUE.
Value
next d permutation(s)/combination(s) sequence for the iterator I
