error using lp function in linux
Hello all, I would like to use the lp function (lpSolve package) on a linux system. Using sample code from the lp function help, I can solve the linear program with no errors or problems. However, when I copy the exact same code to R in linux (after loading the lpSolve package), I get the following error: *** caught segfault *** address 0x3, cause 'memory not mapped' Traceback: 1:

some QCA questions
Dear Adrian Dusa, others, I've recently started to learn R in order to use the QCA package because i think it might offer what other QCA packages don't: possibilities for quite a few conditions and large n. However, can someone tell me approx. how much RAM i need to run QCA on set of +/- 400.000 cases and +/- 15 conditions? (or differently: how much time will it take with RAM of a

up2date upgrade-to-release question
Hi all, I just wanted to ask if anybody did a # up2date --upgrade-to-release=4.1 on CentOS 3.5 box? I did it and I'm having a bit of problems. The box just dies... at intervals between half a day and a couple of days. Initially I considered it was a hw problem, so I had the tech support check it out, and they just switched the box with another, and put the harddisks back on the new box...

The difference is that there is a shift right after the multiply, before the divide. In IR, the difference is: %5 = mul nsw i32 %4, %tmp1

Prime Factorization
Hi everyone, I have a very quick question: Is there a ready-made function in R or any R packages to find the prime factorization of an integer? -- View this message in context: http://r.789695.n4.nabble.com/Prime-Factorization-tp2548877p2548877.html Sent from the R help mailing list archive at Nabble.com.

Problems with lpSolve/Memory ? R crashes
Hello! I have a curious problem, which I cannot solve. With my code I solve thousands of small linear programs with the package lpSolve automatically. But R crashes sometimes (~always, but always on different linear programs) in a strange way. For illustration, I tried to prepare a simple example, which shows the nature of the problem. The function aaa (see below) declares some constants (only in

OT: 4 dual cores agains 2 quad cores
Hi people, Do you have pointers to web documents that help me make comparisons between buying a server with two quad core 2.33 ghz or buying a 4 dual core 2ghz server? I am trying to answer a question of performance. It is not important the redundancy/failover or the price of the server. Just the performance. obviously all the hardware specs are the same, the question is the CPU. --

lpSolve space problem in R 2.4.1 on Windows XP
Hi. I am trying to use the linear optimizer from package lpSolve in R 2.4.1 on Windows XP (Version 5.1). The problem I am trying to solve has 2843 variables (2841 integer, 2 continuous) and 8524 constraints, and I have 2 Gb of memory. After I load the input data into R, I have at most 1.5 Gb of memory available. If I start the lp with significantly less memory available (say 1 Gb), I get

Samba 3.0.0-2 WINS Static entries
Hi, I'm trying to add static entries to the wins.dat file, as per The Official Samba 3 How-to guide but can't get it to work. If I add entries and just leave it be, the server responds with unknown host and If I restart nmbd it removes all the entries (static) that I manually added. Am I doing something wrong or is this a bug ? Brett

Single vs. dual CPUs
I've posted this earlier and have not heard much so far. I'd really appreciate any guidance on this as we are about to order new hardware. We are buying Dell workstations with Red Hat Linux and 64-bit Xeon CPUs to run R. We could add a second processor to each system, or buy slightly faster single CPU systems. Is it possible to make a generalized statement as to what kind of performance

Binary optimization problem in R
Dear all, I would like to solve a problem similar to a multiple knapsack problem and am looking for a function in R that can help me. Specifically, my situation is as follows: I have a list of n items which I would like to allocate to m groups with fixed size. Each item has a certain profit value and this profit depends on the type of group the item is in. My problem is to allocate the items

Hardware Suggestions
We are currently running R under Windows 2000 on a server box running with 2 1.2 GHZ Intel Pentium III Processors. We would like to run this on a new computer running Linux and receive a significant speed increase over our current implementation. Could anyone provide some suggestions for a fast 64 BIT Intel based processor computer with a recommendation for memory and speed/type/number of

[LLVMdev] llvm-java
Hi, Nicolas, I have been talking to Andre about this project. Let me add my two cents: > I don't get it. What is the cons then of a simulation? The tradeoff, IMHO, is as follows: simulation: it does not add instructions to LLVM IR. Instead, it builds an interval representation for each variable. Each interval represents a variable in SSI form, and will be associated to one or

We were able to do this (all the music was preencoded) with 8 machines quite reliably. Basically 4 machines sourced streams, and 4 machines served them.
