Hi, During my recent r2sundials development, I've came across a strange test failing during 'R CMD check' exclusively on win R-devel which I could reproduce with a minimal example that I present here. The toy packages testarma1 [1] and testarma2 [2] are minimal modifications of a skeleton package produced by RcppArmadillo.package.skeleton(). They are almost identical. The first

Hi there, I'm trying to install the package RcppArmadillo in my R 2.11.1 which I installed and regularly update via Ubuntu's repositories. When I try to install RcppArmadillo from CRAN I get: > install.packages('RcppArmadillo', lib='~/myRlibs') [...] g++ -shared -o RcppArmadillo.so RcppArmadillo.o fastLm.o -L/home/matias/myRlibs/Rcpp/lib -lRcpp

Hello, I'm currently working on making Rcpp use the feature described here more: http://cran.r-project.org/doc/manuals/R-exts.html#Linking-to-native-routines-in-other-packages To give more context, Rcpp has for a long time built what we called "the Rcpp user library", i.e. a library we could link against user the linker. We were then producing appropriate linker flag with

What is the RcppArmadillo way to make binomial draws from a vector of probs, similar to what rbinom does in R? Thanx! -- View this message in context: http://r.789695.n4.nabble.com/rbinom-in-RcppArmadillo-tp4683593.html Sent from the R devel mailing list archive at Nabble.com.

Dear all, running the example by D. Eddebuettel (http://dirk.eddelbuettel.com/blog/2011/04/23/) I get an error message. Specifically, the R code I was taking from the above example is ### BEGIN EXAMPLE ### suppressMessages(require(RcppArmadillo)) suppressMessages(require(Rcpp)) suppressMessages(require(inline)) code <- ' arma::mat coeff = Rcpp::as<arma::mat>(a); arma::mat

Hello,?I?am experiencing some difficult time with my R package. Every time I compilei it a hidden file, desktop.ini, is?being created. I am using C++ behind, linkking to Rcpp. The file is generated even when I compile it with?Linux, and in many different computers. Does anybody have any advice or ideas?

Is there anyway with some experience in using armadillo in R C++ extensions? My problem is the following: I programmed a function in a header looking like #include <armadillo> inline arma::vec foo(input) { ... do something return an arma::vec object } compiling this via R CMD INSTALL packagename (PKG_CXXFLAGS = -I/folder/of/armadillo and armadillo_bits in my package) I get the

Dear all, I am testing a simple C++ function that takes a double matrix as argument and which uses routines provided by the C++ Armadillo package. I am aware of the nice capabilities of Rcpp and RcppArmadillo which helps simplifying a lot and that I have already successfully tested. However, I had a hard time trying to figure out how the coercion from a REALSPX matrix to an arma::mat =

I have two questions about the CRAN machines that build binary packages for Mac. When a new version of a package is released, (A) Do the downstream dependencies get re-checked? (B) Do the downstream dependencies get re-built? I have heard (but do not know for sure) that the answer to (A) is no, the downstream dependencies do not get rechecked. >From publicly available information on the

Dear R-devel, I've written a numerical solver for SOCPs (second order cone programs) in R, and now I want to move most of the solver code into C for speed. I've written combined R/C packages before, but in this case I need to do matrix operations in my C code. As I have never done that before, I'm trying to write some simple examples to make sure I understand the basics. I am stuck

Make a reproducible example [1][2][3], because it doesn't happen for me. Then post your example at [4] or [5], because this is the wrong list for this question. You may find that the act of browsing the directory using a GUI is what creates that file rather than the compilation itself.

On a cluster that is based on RedHat 6.2, we are updating to R-3.3.1. I have, from time to time, run into problems with various R packages and some older versions of GCC. I wish we had newer Linux in the cluster, but with 1000s of nodes running 1000s of jobs, well, they don't want a restart. Administrator suggested I try to build with the GCC that is provided with the nodes, which is

Dear R People: Could someone recommend a good c/c++ code (or Fortran) for LU decomposition, please? Sorry to bother about this. I'm trying to do some "non-R" work that requires a matrix inversion.

Hi I tried to use Michael's ppa after having installed Ubuntu 20.04 and R 4, and it seems the ppa is not available now for 20.04, I get message: The repository 'http://ppa.launchpad.net/marutter/c2d4u3.5/ubuntu focal Release' does not have a Release file Am I doing something wrong, or is it correct that it is not available yet? Are there any plans to implement it at some point?

Dear R-devel: The Cluster administrators at KU got enthusiastic about testing R-3.2.2 with Intel MKL when I asked for some BLAS integration. Below I forward a performance report, which is encouraging, and thought you would like to know the numbers. Appears to my untrained eye there are some extraordinary speedups on Cholesky decomposition, determinants, and matrix inversion. They had
