`primes`

is a simple package that does two things; tests for prime numbers, and generates prime numbers. Testing can be done with `is_prime`

, which accepts an integer vector of any length and returns a logical vector of *equal* length containing, for each element, whether it is prime (TRUE) or not (FALSE). `generate_primes`

generates every prime number between `min`

and `max`

, where `min`

is 0 by default.

Both functions rely on a C++ implementation of Wilson's theorem for testing primality; in theory this is a very slow test, but in practice, due to the restrictions R places around maximum integer sizes, it's fast enough for our needs.

For the development version:

devtools::install_github("ironholds/primes")
