similar to: [R] RNG Cycle and Duplication (PR#12538)

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

Unfortunately, RNGkind is buggy. It will not generate warnings except the full name "Buggy Kinderman-Ramage" is supplied for normal.kind. match.arg is supposed to be called before "==" comparison. ======================================== Shengqiao Li Research Associate The Department of Statistics PO Box 6330 West Virginia University Morgantown, WV 26506-6330

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

Hello: Anybody knows how to run Rmpi through PBS (Portable Batch System) on a cluster computer. I'm using a supercomputer which require to submit jobs to PBS queue for dispatching. I tried use mpirun in my PBS script. But all my Rslaves are spawned to the same node. This is not desired. Any suggestions are welcome! Thanks in advance. ======================================== Shengqiao Li

I really like the ease of use with the boxplot command in R. I would rather have a boxplot that shows the average value and the standard deviation then the median value and the quartiles. Is there a way to do this?

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,

Has anyone tried to create dialog boxes for Windows in R so that one doesn't have to type in so much information but rather enter it in a menu-based format. If not, does anyone plan on doing this in the future if it's possible? Thanks. George (Kelley) George A.

I have a set of data in the form x1, y1, z1 x1, y2, z2 ... x1, yN, zN x2, y1, z(N+1) x2, y2, z(N+2) ... x2, yN, z(2N) ...and so on... xM, yN, val(M*N) I have been trying to figure out how to get R to use this data in a persp plot. So far the only thing that I can figure out to do is to break the data file into three different files. The first file contains the x-coordinate data: x1 x2

Samba List: Is anyone out there using AutoCAD R14 and Eagle Point? One of my clients received the latest version of Eagle Point, and the time to load files has become horrible. It has increased from 1 min to 15 min! All files are on the Linux server and the stations we did the initial tests with are PIII w/128MB RAM. The AutoCAD file loads quick, but once the Eagle Point files begin to load

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

Samba users: We have a client we are trying to resolve some Samba transfer problems with. We currently are using a 3Com 3C905B 10/100 NIC which has been successfully configured and works at 100Mbps but doesn't seem to be transferring at what it could be. >From posting another problem I had with a network program, another Samba user mentioned that the 3Com cards don't work best with

Samba Users: One of my clients is using Samba 2.0.3 on Linux 5.0 with approximately 25 clients. This particular client is an architectural and civil engineering group using AutoCAD R12 for all their drawings. One of the add-on programs the civil engineering techs use is Eagle Point of which they just received an "upgrade". Prior to the upgrade load times were acceptable at about one

Samba Users: Here's a summary for several responses I have received since my original posting yesterday. Thanks for your help. Jan Kratochvil had a suggestion on running 'tcpdump' obtained from the Samba site. I did this for the station having difficulty, and the program core-dumped. From reading the resulting output created, that data starts to transfer and then becomes 0000 values.

I'll be moving to Morgantown, WV. Willing to commute to Pittsburgh. But as a programmer I have telecommuted before. see resume at http://www.1wbs1589.info/resume.html

Samba Users: We have Samba v1.9. and are having a small difficulty with the "socket options" and "??? timeout" parameters. When we set it to ?TCP_NODELAY, our log file indicates "Failed to set socket option TCP_NODELAY". This also happened on an earlier version of Samba as well. Has anyone else had a similar problem and found a solution? Also, when setting

Hi all, I have happened to work on MS .NET for sometime now, and I found that this language offers RNG what is called as Donald E. Knuth's subtractive random number generator algorithm (found here: http://msdn.microsoft.com/en-us/library/system.random.aspx#Y12). ? Here I was wondering whether R also have same RNG in it's inventory, so looked at ?set.seed. There I found 2 related RNGs

Kirill, I think some level of collision is actually expected! R uses a 32bit MT that can produce 2^32 different doubles.
