rstream.RNG {rstream} | R Documentation |
The function rstream.RNG(stream)
is used to set a given
"rstream" object stream
as current global R uniform random
number generators.
Without an argument (or NULL
) it returns an "rstream" object
that contains the current global generator.
It is a copy (clone) of the global generator and thus it can be
handled independently from the global generator.
rstream.RNG(stream = NULL)

## create a new rstream.runif object
s <- new("rstream.mrg32k3a")
## use this stream as global R uniform RNG
rstream.RNG(s)
## get a (idenpendent) copy of the stream
## that contains the global R uniform RNG
gs <- rstream.RNG()
## change the state of the global generator
gs <- rstream.RNG()
rstream.nextsubstream(gs)
rstream.RNG(gs)
