Research direction

Start with the linked tree-sitter-r grammar and inspect how existing language parsers are integrated in CodeEditLanguages. Verify the reported syntax-highlighting and symbol-extraction behavior, including R operators and roxygen2 comments, then run the project's existing tests to confirm R support is integrated and working.

Description

Language Name

R

Tree-Sitter Grammar

https://github.com/r-lib/tree-sitter-r

I will work on this

Yes

Additional Info (optional)

R is a widely-used programming language for statistical computing and data analysis. The tree-sitter-r grammar already has SPM support and includes comprehensive syntax highlighting queries.

This would enable R code editing with proper highlighting for functions, variables, operators (including R-specific <-, <<-, |>, pipe operators), keywords, and roxygen2 documentation comments (#').

Implementation is complete and tested - works for extracting symbols by name.
