flowR – sophisticated, static dataflow analyzer

flowR is a sophisticated static analysis framework for the R programming language.

It helps developers and researchers understand existing R code by analysing how values, calls, and control move through a script, making it useful for program comprehension, debugging, and inspection of real-world R sources.

This is free and open source software.

Key Features

• Performs static dataflow analysis for R programs.
• Generates call graphs together with data-flow and control-flow graphs.
• Includes code linting to flag common issues and potential bugs.
• Supports program slicing to reduce a script to the statements relevant to a chosen point of interest.
• Provides a REPL and query interface for exploring analysis results interactively.
• Works with Visual Studio Code, Positron, RStudio, Docker, an R package, and an npm package.
