set.vector.seed {rngwell19937} | R Documentation |
The function allows to seed the generator with a numeric vector of an arbitrary length.
set.vector.seed(seed)
seed |
A numeric or integer vector, whose components have integer values in the interval [0, 2^32-1]. |
Function set.vector.seed()
generalizes the initialization
"mrg32k5a"
for longer seeds.
The input numbers should have integer values in the interval
[0, 2^32 - 1]
. They may be represented by numeric data type
(double precision). If some of the components of the vector seed
is at least 2^31
, then the numeric type is necessary.
If seed
has length 1 and 0 <= seed <= 2^31 - 1
, then
set.vector.seed(seed)
with "mrg32k5a"
initialization
is equivalent to set.seed(seed)
. If seed
has length 1
and 2^31 + 1 <= seed <= 2^32 - 1
, then
set.vector.seed(seed)
with "mrg32k5a"
initialization
is equivalent to set.seed(seed - 2^32)
.
Every two different input vectors of length at most 3 produce different initial states of WELL19937a. The bit pattern of the seed is not important. In particular, the seeds 0, 1, or 2 are not worse than any other seed and produce unrelated sequences.
NULL
invisibly.
