Tools for R programmers

Code formatting

• styler: formats R source files, packages, and supported literate-programming documents according to a configurable style.

Linting and static analysis

• lintr: static analysis for style, syntax, and selected semantic problems. It can be run from an editor, the R console, or continuous integration.

Package and environment management

• renv: creates a project-local R library and lockfile so that package versions can be restored on another system. It records the R version but does not install R itself or manage compilers and system libraries.
• pak: fast package installer with dependency resolution and support for CRAN, Bioconductor, Git repositories, URLs, and local packages. It complements rather than replaces an renv lockfile.

Testing

• testthat: testing framework for R.

Package development and documentation

• usethis: automates repetitive project and package setup tasks.
• devtools: convenient interface to common R package development, checking, testing, and documentation tasks.
• roxygen2: generates R package reference documentation and namespace information from comments beside the code.

Profiling

• profvis: interactive visualization of profiling data collected by R's sampling profiler.

Language interoperability

• Rcpp: allows you to write C++ code that can be called from R.
