⚠️There's a newer version (0.6.6) of this package.Take me there.

CodeDepends (version 0.6.5)

Analysis of R Code for Reproducible Research and Code Comprehension

Description

Tools for analyzing R expressions or blocks of code and determining the dependencies between them. It focuses on R scripts, but can be used on the bodies of functions. There are many facilities including the ability to summarize or get a high-level view of code, determining dependencies between variables, code improvement suggestions.
