Ma premi??re question: puis-je ??crire en fran??ais, mon anglais est pire que pire. J'essaie en fran??ais; sinon, j'essaierai une traduction! Je sduis d??butant. Ma question est donc simple, j'imagine. Je travaille sur des tableaux de statistiques. Je prends un exemple: J'ai un "frame" que j'appelle "eurostat" qui me donne des statistiques

I'm a new R user so this is possibly a naive question. I'm trying to load an external CSV file into a dataframe using: df_name<-read.table("myfile.csv") myfile.csv should have 5 elements per row, though a percentage are missing the last two elements (the commas are present as placemarkers). However, R does not create the dataset but returns the message: line 1

I noticed one of my smbd processes for one particular client (IUSR_JUNIPER) is taking 200MB in memory, far different from all the other smbd processes. Should I be concerned about a memory leak here? I don't think samba would be caching any files, so I can't see why it'd use this much memory. That windows client is a win2k IIS5 server, with well over 60 sites that are hosted off a

Hello All, In general when we use Rprof for performance evaluation on Multicore systems the output provides the time on the basis of the "user" time and the sampling time is equal to the the user time as reported by system.time. This does not seem right behavior when R is linked to BLAS/Lapack or other libraries which are optimized for parallel or multicore architectures as

Hello All, I have been trying to figure out on linking R with an external lapack. Even though the R-admin recommends against doing so, our requirements force us to link it to an external lapack. I am running configure with the following parameter. *./configure --with-lapack="-L/usr/lib -llapack -lcblas" * The above seems to be having NO effect. However, later I tried

Recently had passthrough of 2xPCI DVB-T cards and 1xPCIe DVB-S2 card working, the last know config that was *certainly* working was dom0 xen-4.1.1-3.fc16.x86_64 kernel-3.1.0-0.rc7.git0.0.fc16.x86_64 domU kernel-3.1.0-0.rc8.git0.0.fc16.x86_64 Since then I''ve updated xen-4.1.1-6.fc16.x86_64 on dom0 kernel-3.1.0-0.rc9.git0.0.fc16.x86_64 on dom0 and domU and updated all other packages

I have put two workgroups in the global area but it only shows the second one

Whenever I try to start mongrel, I get an exception about "can''t modify frozen string". I get a similar exception when I try to do "rake db:migrate". In this case, the exception seems to pop up *after* the migrations do succesfully

Hi list, Please tell me why sometimes RSymphony.dll crashes on Windows 7 (may be on other Windows too). I saw that it depends on input data. For example this code bring to crash: library('Rsymphony') mat = c(0, 1, -100.37967, 0, 0, 1, 0, 0, -200, 0, 0, 1, -0.4, 0, 0, 1, 0, 0, -0.4, 0, 0.5, 0, 0, 0, 0, 0, -1, 0, 0, 0) mat = matrix(mat, nrow=6, byrow=TRUE) mat dir = c("=",

Good Evening Does anyone in the R-help list have experience writing an R wrapper that interfaces with the commercial packages LINGO and/or LINDO.api from R? I have a set of nonlinear/mixed integer problems that solve nicely with LINGO but I would like to use R to set the problems up and analyze/plot the solutions dynamaically. I have searched the archives and have not found any R packages that

Dear everyone, I don't know much about Integer Programming but am afraid I am facing a problem that can only be solved via Integer Programming. I was wondering if those of you who have experience with it could recommend an R package. I found the following R packages: Rglpk glpk lpSolve lpSolveAPI Are there any others? Are some of them easier to use than others for a beginner? Any advice

I'll appreciate the help on the following problem: I solved many Nonlinear programming problems with nonlinear constraints....Rdonlp is working well but i am unable to get INTEGER data with nonlinear constraints in Rdonlp. Is it possible to get Integer Values of parameters in any package of R with nonlinear constraints. Rahul [[alternative HTML version deleted]]
