[Rcpp-devel] Is there an easy way to convert Rcpp code to pure cpp code to build a command line tool

Dear List, This is probably a dumb question: Is there an easy way to convert Rcpp code to pure cpp code to build a command line tool? I was thinking about something similar to the 'python setup.py install’ thing. Once the software is built, the binary executable can be added to /usr/bin/ and

[Rcpp-devel] deprecated log_max warning

Dear List, Just a super naive (dumb) question: after upgrading to RcppArmadillo_0.6.700.3.0 Rcpp_0.12.4, I receive compilation warning ''log_max' has been explicitly marked deprecated here” on every line of my code that uses ‘trunc_exp’ or ‘trunc_log’. I wonder how to fix this. The code to rep

[Rcpp-devel] clang-omp and clang++ -fopenmp compiler (OS X)

Dear List, I’m new to openmp and wonder if anyone know how to add -fopenmp to clang++ such that it can compile successfully without error using sourceCpp. Using the dmvnorm_arma as example (http://gallery.rcpp.org/articles/dmvnorm_arma/ ): I got

[Rcpp-devel] failed to compile code on the server with simple operations on matrices with type fmat {RcppArmadillo}

Dear List, I’m having an issue with compiling Rcpp code using ‘fmat’ matrix type on the server (Linux distro: CentOS release 5.11 (Final)) and wondering if someone has a quick fix. Basically, the following code works fine on my Macbook (R 3.2) but not on the server (Run/sessionInfo pasted). A

[Rcpp-devel] float for BigMatrix

Dear List, I wonder if there is a way to convert a big matrix to ‘float’ instead of ‘double’ within a Rcpp program. The reason for using float is mainly for performance improvement. For instance, I have a simple function named ‘print_bigmat’ as shown below. As shown in the output, ‘double_bigm

[Rcpp-devel] examples of using cula matrix multiplication in Rcpp

Dear List, I wonder if anyone worked on incorporating CULA tools library functionality into Rcpp. How much speed gain on top of Rcpp do we expect on basic operation like matrix multiplication? In particular, I’m currently usnig RArmadillo to seamlessly perform matrix multiplication. But the s
