Seeding the Default RNG with a Numeric Vector
Original language description
A function setVectorSeed() is provided. Its argument is a numeric vector of an arbitrary nonzero length, whose components have integer values from [0, 2^32-1]. The input vector is transformed using AES (Advanced Encryption Standard) algorithm into an initial state of Mersenne-Twister random number generator. The function provides a better alternative to the R base function set.seed(), if the input vector is a single integer. Initializing a stream of random numbers with a vector is a convenient way to obtain several streams, each of which is identified by several integer indices.

Funkce poskytuje lepší kvalitu inicializace náhodného generátoru než standardní funkce set.seed() a umožňuje snadněji vytvořit několik nezávislých posloupností náhodných čísel.
