similar to: Rcpp package relaunched

Hi, I'm a bit puzzled. I uses exactly the same code in RcppExamples package to try adding RcppFrame object to RcppResultSet. When running it gives me segmentation fault problem. I'm using gcc 4.1.2 on redhat 64bit. I'm not sure if this is the cause of the problem. Any advice would be greatly appreciated. Thank you. Rob. int numCol=4; std::vector<std::string>

Hi, Im not sure if this is the right place to post this. I am using Xubuntu Karmic Koala and am trying to use the Rcpp package. I am testing it using a simple code that takes in a vector and adds 1 to each element: #include <Rcpp.h> // This file takes in a vector and adds one to each entry RcppExport SEXP addone(SEXP vec){ // create a local copy of vec Rcpp::NumericVector

Hi, I was trying to generate RcppDatetime from a string. The main problem for me is that my string contains millisecond. I saw that RcppDatetime takes in double of seconds since epoch. I try to generate a double using boost but has no success. I'm wondering if you have any sample snippet? The string looks like: "2010-03-18 15:50:51.232" Secondly, what time zone RcppDatetime is

Hi, I am Linux Ubuntu 9.04 user. I'm using R-2.6. Actually, I am developing R package for reading/writing 3D images. I needed to use the R package Rcpp in order to make profit of available C/C++ codes. My problem is that my C code is not able to include the Rcpp.h In fact, when I run this command R CMD build rply, I got the following error message in the file

It appears that my archived packages Rcpp and RcppTemplate have been removed at CRAN, yet they appeared in the CRAN archives until recently. What is the CRAN policy on archives and removal? Thanks, Dominick [[alternative HTML version deleted]]

Hi I'm trying to implement something similar to the following R snippet using C. I seem to have hit the wall on accessing class slots using C. library(fPortfolio) lppData <- 100 * LPP2005.RET[, 1:6] ewSpec <- portfolioSpec() nAssets <- ncol(lppData) setWeights(ewSpec) <- rep(1/nAssets, times = nAssets) ewPortfolio <- feasiblePortfolio( data = lppData, spec = ewSpec,

I wrote the Rcpp library and the RcppTemplate package to make it easier for developers to contribute packages to the R community. In addition to providing detailed documentation on package creation it provides a clean object mapping between R anc C++ that helps developers to implement packages that benefit from the performance of C++ and the flexibility of R. The package named 'Rcpp' was

Just a note to anyone in the Kansas City area that I've relaunched the KCAUG website/group at http://kcaug.org. Please drop by and join the group. :) -- Kyle Sexton

Hello, we are on the way to relaunch winetools for 0.9. One problem remains unsolved: Whenever we start Word 2k, it states "Preparing installation..." and "Please wait till office completes the installation..". It does so and we have a working Word. But is it annoying that is done on every single start of Word. All other Office2k apps perform very well. Regards Joachim von

The documentation tells the overlay is > removed when the handle to libguestfs is closed. Right, the overlay is created by libguestfs itself and thrown away when the handle is closed:

It's possible through the API to do a sequence of calls like this: g = guestfs_create (); guestfs_add_drive (g, "foo"); guestfs_launch (g); guestfs_shutdown (g); guestfs_launch (g); # relaunch the handle The question is, what should be the state of the handle at the second launch? Would the verbose flag still be set if it had been set earlier? (I think fairly

How do you refresh a stream without relaunching, we would like to add new mp3 into a root folder using m3u. We get that the m3u needs to be updated but cant figure out how to use " http://172.31.145.234:8000/admin/updatemetadata.xsl?mount=/stream" For example the file would be: thisband - greatsong.mp3 as below *MPG Radio *|* BandFan | *bandfanforum at gmail.com Founded in 2012,

This would be easier if base::set.seed() accepted a value of .Random.seed instead of just a scalar integer or, new to R-3.0.0, NULL. If set.seed() returned the previous value of .Random.seed (NULL if there was no previous value) things might be even easier. People should not have to know where .Random.seed is stored. S+'s set.seed() accepts a value of .Random.seed but does not return the

Hello. I am trying to include R in an eclipse C++ project so that I can use Rcpp and Rinside. Right now I have R installed on my Ubuntu machine and both plugins are installed too. I have the directories of the corresponding .so files set in the Project > Properties > Settings Gcc c++ linker under Library Search Path. Here is the error that I'm getting when I try to build my code: >

Hi, I have an implementation where I transfer data records via shared memory to an R program. If anyone has prior experience, I'd like to find out which would be faster 1) storing data records in shared memory as they are(in a matrix) and then use the Rcpp::wrap to convert them to R datatypes 2) merge the records into a string and store records as strings. Then use R functions like

I have spent some hours browsing the RInside and rcpp documentation, lots of it; but ... as a programmer of C++ since 1990, on both Windows and Unix ... ( Solaris and Ubuntu, and Mandrake/Mandrivo Linux); I see a minor problem ...... Where is the rcpp.h header file?? The below code fails to compile as the RInside.h header file references the rcpp.h header file, which is not included with
