similar to: Replacing the Random Number Generator in Stand Alone Library

Hi, I'm seeing something that may be a bug in R's standalone math library, which is packaged by Debian as r-mathlib. I reported it to the Debian BTS as http://bugs.debian.org/657573 I'm using Debian squeeze, and the code was tested with r-mathlib 2.11.1-6 (default on stable) and 2.14.1-1 (from testing/unstable). I summarize this report below. The following code with the R math

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

Hi, I have a few questions about the RNG in R; apologies if these are dumb questions: 1. It is my understanding that, among the three types of random number generators available in R now, the best one is the Marsaglia Multicarry. Is this correct? 2. How does the best RNG in R compare (in terms of quality) to the RNG in SPlus? (based on Marsaglia's Super Duper)? Does the Super-Duper in

Brian I've been playing a bit with the Wichmann-Hill RNG. I would prefer to have normally distributed random numbers and I think I have things generally worked out to use Wichmann-Hill and then Box-Muller. In the process, I was looking at R's rnorm.c, but could not figure out what transformation is used in R to convert uniform rv's to normal rv's. Do you know? It looks like there

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 (Knuth)] . Is there any other

I sent this to R-devel early last month, but have received no response, so I guess it really is a bug. This looks like a bug to me, and is a bit hard to describe, but easy to reproduce. ? Basically, if RNGkind is saved as something other than the default, and if the first operation in a session is a set.seed(), the default is reverted to. ?Reproduce by: cafe-rozo> ?R --vanilla R version

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

Full_Name: Richard Simard Version: OS: Linux Submission from: (NULL) (132.204.25.139) In the random number generator MARSAGLIA_MULTICARRY, your algorithm is different than the one in the original reference that you give in the R manual: Marsaglia in his post to the mailing list {\it sci.stat.math} on September 29, 1997. The last line in the R program has a ^ while Marsaglia's algorithm has

Dear R-developer (Marsaglia??) The following piece of code from package SuppDist , routine "dist.cc" seems to have a bug ULONG MWC1019(void){ ULONG long t; int i = endQ-1; t = 147669672LL*Q[i] + Q[endQ]; Q[endQ] = (t>>32); if(i>0) return(Q[i--] = t); i = endQ-1; return(Q[0] = t); } in fact , being "i" a local variable that have automatic storage, it is

I am writing a function for the purposes of a simulation. Due to memory problems, the function sometimes crashes. In order to get around this problem, I would like to include to be able to save the "last" seed, so I can pick up with the next run of the simulation after a "crash". I am having trouble understanding what is going on with .Random.seed! For each run of the

I'm running into problems with set.seed--maybe I'm misunderstanding something. I'm running R 1.5.1 on Windows 2000. I'm basically trying to capture the random seed so that I can reproduce a simulation if it's necessary later. Using set.seed, I can certainly get reproducible results, but not the results I get on the first pass. Here's an example: # Generate a random

Hello, When I mount a cifs share from Windows server onto a linux client, all I am interested in is sid to uid and gid and vice versa mapping. Can I accomplish that using just windbind and not samba server and nmbd i.e. have a windbind.conf file with the pertinent stanza! Say I just give the Windows share server name/ip address and sid to winbind deamon via one of its existing APIs, can it
