Rcpp Interface to the APT Package Manager
The APT Package Management System provides Debian and
Debian-derived Linux systems with a powerful system to resolve package
dependencies. This package offers access directly from R.

'Rcpp' Interface to the APT Package Manager

The 'APT Package Management System' provides Debian and
Debian-derived Linux systems with a powerful system to resolve package
dependencies. This package offers access directly from R.  This can
only work on a system with a suitable 'libapt-pkg-dev' installation
so functionality is curtailed if such a library is not found.

Tools for Combinatorics and Computational Mathematics
Provides optimized functions implemented in C++ with 'Rcpp'.
There is a generalized combinations function that is highly efficient
(both speed and memory). There are optional contraint arguments that
when employed, generate all combinations of a vector meeting a specific
criteria (E.g. finding all combinations such that the sum is less than
a bound). Additionally, there are various sieving functions that quickly
generate essential components for problems common in computational
mathematics (E.g. number of comprime elements, divisors, prime
factorizations, and complete factorizations for many numbers as well
as generating primes in a range).
