Well, that's how it was in the past.\n\nEnter checkmate.\n\nVirtually **every standard type of user error** when passing arguments into function can be\ncaught with a simple, readable line which produces an **informative error message** in case.\nA substantial part of the package was written in C to **minimize any worries about execution time overhead**.\nFurthermore, the package provides over 30 expectations to extend the popular [testthat package](https://cran.r-project.org/package=testthat) for unit tests.\n\n\n## Installation\nFor the stable release, just install the latest version from [CRAN](https://cran.r-project.org/package=checkmate):\n```{R}\ninstall.packages(\"checkmate\")\n```\nFor the development version, use [devtools](https://cran.r-project.org/package=devtools):\n```{R}\ndevtools::install_github(\"mllg/checkmate\")\n```\n\n## Resources\n* [R Journal Paper](https://journal.r-project.org/archive/2017/RJ-2017-028/index.html)\n* [NEWS](https://github.com/mllg/checkmate/blob/master/NEWS.md)\n* [Documentation/Vignettes](https://mllg.github.io/checkmate/)\n* [Grouped function reference](https://mllg.github.io/checkmate/reference/checkmate-package)\n","funding_links":[],"categories":["R"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmllg%2Fcheckmate","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmllg%2Fcheckmate","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmllg%2Fcheckmate/lists"}
