rngSetSeed-package {rngSetSeed}

Seeding the Default RNG with a Numeric Vector

Description

The function setVectorSeed(vseed) is provided, which allows to initialize the R base Mersenne-Twister random number generator using a numeric vector vseed of an arbitrary nonzero length. The transformation of vseed into the initial state of Mersenne-Twister is computed using AES (Advanced Encryption Standard). The precise algorithm is described in generateInitialization.

The directory "rngSetSeed/tests" contains tests, which

(1)

compare the generated random numbers to stored precomuted ones,

(2)

compare the initial states obtained using AES in C-level functions with initial states obtained using a (slow) implementation of AES in R-level functions included for test purposes.
