S4-class for Exposing C++ ComboGroups Class

The ComboGroups class is an S4-class that exposes C++ classes that provide access to iterators and other useful methods.

Slots

nextIter

Retrieve the next lexicographical result

nextNIter

Pass an integer n to retrieve the next n lexicographical results

nextRemaining

Retrieve all remaining lexicographical results

currIter

Returns the current iteration

startOver

Resets the iterator

sourceVector

View the source vector

summary

Returns a list of summary information about the iterator

front

Retrieve the first lexicographical result

back

Retrieve the last lexicographical result

randomAccess

Random access method. Pass a single value or a vector of valid indices. If a single value is passed, the internal index of the iterator will be updated, however if a vector is passed the internal state will not change. GMP support allows for flexible indexing.
