random | R Documentation |
Functions for generating and working with truly random seeds.
random.org(n = 10, rnd = "new")
urandom(n = 10)
rngControl(expr, seed = NULL)
rngSeeds(n, seed = NULL)
n |
Number of integers required. |
rnd |
random.org parameter |
expr |
Expression to be evaluated with RNG control. |
seed |
RNG seed. |
random.org
gets seeds from random.org.
urandom
gets seeds locally from ‘/dev/urandom’ on *nix systems.
rngControl
is a function to control RNG for the evaluation of an expression.
rngSeeds
generates RNG seeds using sample.int
.
It is included for situations when neither random.org
nor urandom
is available.

random.org(n=5)
seed <- urandom(n=1)
seeds <- rngSeeds(5,seed=seed)
set.seed(seed)
runif(5)
rngControl(runif(5),seed=seed[1])
rngControl(runif(5),seed=seed[1])
runif(5)
set.seed(seed)
runif(5)
runif(5)
