  • First we claim

    • current_dir = Your current directory
    • pkg_name = The name of your package

  • On an active R console, run

require(Rcpp)
require(RcppArmadillo)

RcppArmadillo.package.skeleton(pkg_name)
  • change dir to package directory, and
    • put .cpp file under dir ./src
    • put .R file under dir ./R start a new R session and run
compileAttributes(verbose=TRUE)

Then run

library(tools)
package_native_routine_registration_skeleton("~/Downloads/regboost")
  • Switch back to the mother folder of your package, run the following code from terminal
R CMD build pkg_name
R CMD INSTALL pkg_name_1.0.tar.gz

Then open a new R session, run

require(pkg_name)

Chicken dinner!
