When the parallel package is used, setting the RNG seed for reproducibility
involves more than simply calling set.seed(). set.rseed takes
care of the additional overhead.
set.rseed(seed)seed for the random number generator
If the parallel package is not on the search path, then set.seed() is called.
If parallel is on the search path, then the RNG kind is set to "L'Ecuyer-CMRG",
the seed is set and mc.reset.stream is called.
# These should give identical results, even if the `parallel' package is loaded.
set.rseed(123); do(3) * resample(1:10, 2)
#> Using parallel package.
#> * Set seed with set.rseed().
#> * Disable this message with options(`mosaic:parallelMessage` = FALSE)
#> V1 V2
#> 1 5 6
#> 2 5 4
#> 3 4 7
