similar to: suggestions argument in rbga function in genalg package

Hi all. I would like to use the rbga.bin function (from the "genalg" package) as part of a model selection process to whittle down a list of ~40 potential explanatory variables to only the most important ones. Unfortunately, despite my working knowledge of R for linear modeling and basic statistics, I cannot understand the two examples provided with the documentation for rbga.bin

Thank you Lang. I attached the ELF object file here for your reference. Here is the IR dump of JittedOpExpr LLVM function. IrExprGetValue1 LLVM function calls to external function expr->evalfunc(expr, econtext, isNull, isDone); which should be pointed by 0x7fe4801fa1f8. However, only the first time MCJIT generated object point to expr->evalfunc but second time when program load from object

Hi I am first looking at genalg as a starting point for GA implementation in R. I have a couple of questions regarding this package and GA implementation in general. If you could provide some hints on these questions, I would really appreciate. Thank you in advance. 1. I found two methods for performing optimization based on the type of chromosome encoding, i.e. binary and float. I'm

Dear R devel, being constrained to a windows environment at work and having colleagues being accustomed to the Microsoft Office Suite, I was looking for a way to have the RweaveLatex driver for Sweave automatically generating 'win.metafile's in addition to the pdf graphics. Without this functionalilty, the generation of emf-graphics is quite laborious, I think: <<>>= plotit

Hello R-Help I have a question about the "behind the scenes" behaviour of the Rscript -e command and particularly its interaction with Sweave and tempdir(). We are trying to deploy R as a web service to do water quality analyses and have been writing software to call Sweave via Rscript eg: cmd> Rscript -e Sweave('sweavefile.Rnw') One problem we have been having is that

Hi, All I have a problem to reuse mcjit jitted code loaded from ObjectCache from a file. In the first run, I use MCJIT generate function JittedOpExpr object code as following and it runs OK. 0x7fe4801fa1f8 at instruction 0x00007fe4cc6c2014 points to 0x69382E which is the beginning of ExecEvalVar function. Then I save the object code into a file after implementing notifyObjectCompiled method.

Dear R community, I am trying to write my own user defined split function for rpart. I read the example in the tests directory and I understand the general idea of the how to implement user defined splitting functions. However, I am having troubles with addressing the data frame used in calling rpart in my split functions. For example, in the evaluation function that is called once per node,

Hello It seems that sweave always runs in the global environment. I want to run sweave from within a function, and pass a variable into sweave, however when I do this, sweave doesn't see the variable. Here's my example test_sweave.Rnw file |% \documentclass[a4paper]{article} \usepackage[OT1]{fontenc} \usepackage{Sweave} \begin{document} \title{Test Sweave Document} \author{Paul

Hello list, I am dealing with a noisy function (gradient,hessian not available) with simple boundary constraints (x_i>0). I've tried constrOptim() using nelder mead to minimize it but it is way too slow and the returned results are not satisfying. simulated annealing is so hard to tune and it always crashes R program in my case. I wonder if there are any packages or functions can do

Hello, all experts, My major is computer-aied drug design ( main QSAR). Now, my paper need be reviesed, and one reviewer ask me do genetic algorithm coupled with gaussian process method (GA+GP). my data: training set: 191*106 test set: 73*106 here, I need use GA+GP to do variable selection when building the model. In R, there are not GA package like in matlab

Hi All Please see the Rprofile file which i have modified as follows and after that when I start R then I see that R says to me "TRUE" for all the packages implying that all loaded at once. But when i try to use commands as simple as help("lm"), it doesnt work nor any of the menu "Packages" is not working. Although the regression using lm ( Y ~ X ) is working
