Initialization of the R base random number generator Mersenne-Twister with a vector of an arbitrary length..

http://cran.r-project.org/web/packages/rngSetSeed

The package provides a function setVectorSeed(vseed). Its argument is a vector of arbitrary nonzero length, including length 1, whose components have integer values from [0, 2^32-1] and which is used to initialize the R base Mersenne-Twister random number generator. In order to guarantee that different input vectors yield unrelated streams of random numbers, a random number generator based on AES (Advanced Encryption Standard) is used for the transformation of vseed into the initial state of Mersenne-Twister. Due to the use of AES, the function provides a better alternative to R base function set.seed() even if vseed is a single integer. Initializing random number stream with a vector including a reproducible index of an R process allows to use reproducible and unrelated streams of random numbers in several independent R processes. The package contains test scripts, which verify its installation by comparing the output with a stored precomputed one and by comparing the encryption provided by C-level AES with an implementation of AES at the R-level, which is included for test purposes. See CRAN package "randaes" for a random number generator based purely on AES.
