I have commited fixes for 0.64.1 for
(1) From: Mai Zhou <mai@ms.uky.edu>> .Random.seed <- c(1, 1:2)
> .Random.seed
[1] 1 1 2> runif(5)
Warning: Wrong length .Random.seed; forgot initial RNGkind? set to
Wichmann-Hill[1] 0.02253721 0.84832584 ........
Here the length of the seed was being tested before the kind was
picked out, so the length of the previous type was used.
(2) > .Random.seed <- c(0, 30269, 30307, 30323)
> runif(1)
[1] 0> .Random.seed
[1] 0 0 0 0
and it remains zero thereafter.
This was particularly invidious as the help has said (for a long time,
despite my commenting several times, even in the `R Complements')
The seed, `.Random.seed[-1] == r[1:3]' is an
integer vector of length 3, where each `r[i]' is
in `1:p[i]', where `p' is the length 3 vector of
primes, `p = (30269, 30307, 30323)'. The
This should be (and will be) 1:(p[1] - 1).
(3) The help page now says what the length of the seed is and the
restrictions for the "Marsaglia-Multicarry" and
"Super-Duper" kinds
and corrects the description of the latter.
