rustr

R rust port

Goal

• Modernize C based R code base using Rust
• Reimplement src/main
• Do not touch performance-critical code such as math functions written in Fortran.

Status

• Only front-end is ported in Rust.
• R will be incrementally ported.

Build

# set R 4.2.0
echo "4.2.0" > R_VERSION

# build
cargo build

Run

# Run wrapper script to setup environment and run rustr
./script/run_r.sh
