Setting RNG Seeds
.setRNG is an S4 generic that sets the current RNG settings, from a
variety of specifications.
Its methods define the workhorse functions that are called by setRNG.
.setRNG(object, ...) ## S4 method for signature 'character' .setRNG(object, ...) ## S4 method for signature 'numeric' .setRNG(object, ...)
object |
an R object from which RNG settings can be extracted, e.g. an
integer vector containing a suitable value for |
... |
extra arguments to allow extension and passed to a suitable S4 method
|
"character": Sets the RNG to kind object, assuming is a valid RNG kind:
it is equivalent to RNGkind(object, ....
All arguments in ... are passed to RNGkind.
"numeric": Sets the RNG settings using object directly the new value for
.Random.seed or to initialise it with set.seed.
# set RNG kind
old <- setRNG('Marsaglia')
# restore
setRNG(old)
# directly set .Random.seed
rng <- getRNG()
r <- runif(10)
setRNG(rng)
rng.equal(rng)
# initialise from a single number (<=> set.seed)
setRNG(123)
rng <- getRNG()
runif(10)
set.seed(123)
rng.equal(rng)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
