Compiling R on Sunos
I'm looking for some help in getting R to compile on Sunos. We run a
collection of Sunos and Solaris machines in the department here. I got
to compile on Solaris 2.5.1 using gcc 2.7.2.2. On my Sunos 4.1.3 (and
I've tried it on Sunos 4.1.4 as well) machines, it crashes during the
compile. I'm using gcc 2.8.1 on there. It gets to this point:
gcc -g -O2 -I../include

user supplied random number generators
?Random.user says (in svn trunk)
Optionally,
functions \code{user_unif_nseed} and \code{user_unif_seedloc} can be
supplied which are called with no arguments and should return pointers
to the number of seeds and to an integer array of seeds. Calls to
\code{GetRNGstate} and \code{PutRNGstate} will then copy this array to
and from \code{.Random.seed}.
And it offers as an example

Wichmann-Hill Random Number Generator and the Birthday Problem
Dear all,
Recently I am generating large random samples (10M) and any duplicated
numbers are not desired.
We tried several RNGs in R and found Wichmann-Hill did not produce
duplications.
The duplication problem is the interesting birthday problem. If there are
M possible numbers, randomly draw N numbers from them,
the average number of dupilcations D = N(N-1)/2/M.
For Knuth-TAOCP and

RNG Cycle and Duplication
Hello all,
I am generating large samples of random numbers. The RNG help page says:
"All the supplied uniform generators return 32-bit integer values that are
converted to doubles, so they take at most 2^32 distinct values and long
runs will return duplicated values." But I find that the cycles are not
the same as the 32-bit integer.
My test indicated that the cycles for

As mentioned on Twitter, I think the following behavior should be fixed
as part of the upcoming changes:

bias issue in sample() (PR 17494)

I don't doubt this is expected with the current implementation, I doubt
the implementation is desirable. Suggesting to turn this to
pbirthday(1e6, classes = 2^53)
## [1] 5.550956e-05
(which is still non-zero, but much less likely to cause confusion.)

unexpected behaviour of rnorm()
Hello everyone.
If I do
f <- function(n){max(rnorm(n))}
plot(sapply(rep(5000,4000),f)) #[this takes my PC about 30 seconds]
then I get something quite unexpected: gaps in the distribution. For
me, the most noticable one is at about 3.6.
Do others get this? Is it an optical illusion? It can't be right,
can it? Or maybe I just don't understand the good ol' Gaussian very

R questions
Dear Sir/Madam,
I am a beginner in R. Here is my questions.
1. Can you give me one test for randomness (a name and descriptive
paragraph is sufficient).
2. I have learned a uniform random number generator [e.g. not the
algorithms: i)Wichmann-Hill, ii) Marsaglia-Multicarry, iii) Super-Duper
(Marsaglia), iv) Mersenne-Twister, v) TAOCP-1997 (Knuth), or vi) TAOCP-2002

RNG R/Splus compatibility
Starting with example Wichmann-Hill code from Brian Ripley I have been playing
with a set of programs for getting the same random sequences from R and Splus. A
copy is included below along with a test (which works in Solaris with R and
Splus 3.3).
The approach is somewhat different from the usual problems on this list as I am
trying to get the same results from Splus as I get from R. However,

I'm using Debian squeeze, and the code was tested with r-mathlib 2.11.1-6

Hi,
Our department has detected a bug in the implementation of the
Kinderman-Ramage generator for normal random variates in version

close to 0.)
We have already encountered this bug in version 1.6.2

Replacing the Random Number Generator in Stand Alone Library
Hi R-Developers,
I had a question about the random number generator used in the R StandAlone
Math Library. The stand-alone library depends on the unif_rand() function
for most simulated values, and this function is provided in the sunif.c file
in the relevant directory. At present, this program implements the
"Marsaglia-Multicarry" algorithm, which is described throughout the R

Rejoin dc to domain
I'm in no position, at the time being, to be of any good help and give advice. Sorry for that.
Try do a meta data cleanup "the GUI way"; check DNS, System container, AD sites and services etc. And remove any remains of the old DC.
