Dear all. I have data with 2 variable x,y size 10000. I want to sampling from this data with size 100. How I can do it. THANK. -- Jumlong Vongprasert Institute of Research and Development Ubon Ratchathani Rajabhat University Ubon Ratchathani THAILAND 34000 [[alternative HTML version deleted]]

Hi I get huge memory leaks using LLVM IRBuilder (trunk version) Basically I recreate a function over and over again, and pretty sure that my code doesn't cause the leak while(true) { Function *fn = module->getFunction(name); if (fn) fn->eraseFromParent(); fn = cast<Function>(module->getOrInsertFunction(name, fnType)); fillFunction(fn); //Fill function with

Hello Everyone,   This is my first attempt to do something in R. As a precursor to a Willingness to Pay analysis, I want to conduct a Mixed Conditional Logit analysis but am unsure how to proceed because of some nesting within my data.   Below is some data and code that illustrate what I’m trying to do. The data are based on responses to a conjoint survey obtained during pilot testing. In the

How can I best achieve the following (works in Splus): filenames <- dos("dir *.sasb7dat /b") What I am asking, more generically, is: how can I capture the output of a DOS command in R? I have tried using system("COMMAND.COM /c dir /b", intern=T, show.output.on.console=T) where intern: a logical, indicates whether to make the output of the command an R

Hello I have the following scenario, and I am not sure why the performance is so bad (take 30 minutes to complete with very simple generated functions): 1. Create module 2. Do something like EE = EngineBuilder(theModule).setEngineKind(EngineKind::JIT).create(); 3. Create a function in the module: theModule->getOrInsertFunction(..) 4. Execute 1000 times the function using

Hi, I just encountered a problem in R that may easily be fixed: If one uses attach for a data.frame e.g. 10000 times and forgets detach, then R gets incredibly slow (less then 10% of the original speed).

I've searched on CRAN for axes, axis, and other terms I've already forgotten, without (re)discovering the reason for S using "non-joining" axes by default, instead of box("l"). MASS points me towards Cleveland (1993) but I don't have ready access to this any more. Could someone give me a one-liner to justify this choice to a sceptic? It's something to do

(If this only happens in Win 98, I'm sure I could live with it. Just may be helpful to report it, I hope.)

Greetings everyone, I am new at R. My questions is rather basic. Looking R manuals looks like there should be a way to read MS excel files into R. Could somebody tell me which library should I use for that? Thanks in advance Victor H.
