RcppProgress

a R package that provides a c++ interruptible progress bar with OpenMP support for c++ code in R packages:

• check for user interrupts in your c++ code
• display a progress bar monitoring your c++ computation
• compatible with multi-threaded c++ code (e.g. openMP)

Installing

• from CRAN: install.packages("RcppProgress")
• from github: remotes::install_github('kforner/rcpp_progress')

example

see a detailed example on Rcpp Gallery: http://gallery.rcpp.org/articles/using-rcppprogress/

How to build

Prerequisites:

• OpenMP support to use the multithreaded parallelized version. OpenMP is available in GCC >= 4.2

Just install it the usual way.

If you want more control, unarchive it, cd to the source directory, then type R CMD INSTALL . in the console.

For developers

tests and check

If you have all the RcppProgress dependencies (and suggests) installed:

type:

• make tests: to run the tests
• make check: to check the package

docker-checker

A Dockerfile (<docker_checker/Dockerfile>) is provided to help building the dev environment (built on rocker/r-devel) in which to develop and test RcppProgress.

type:

• make docker/build: to build the docker
• make docker/run: to run a shell in the docker with the current dir mounted inside
• make docker/check: to check the package inside the docker
• make docker/tests: to run test tests of the package inside the docker

test on windows using rhub

make docker/run
