The same integers as R's .Random.seed: the kind code (10403 for R's default,
403 with sampleKind: "Rounding", 10407 for L'Ecuyer-CMRG), followed by 625 integers
for Mersenne-Twister or 6 for L'Ecuyer-CMRG (unsigned seeds of 2^31 or more appear as
negative numbers, as in R). Pass it to setRandomSeed to restore the state.
Returns a copy of the current generator state, as reading R's
.Random.seeddoes. Equivalent to R's.Random.seed.
