Note that only double precision routines are provided byR. The buildscript for this particular crate owes a lot tolibR-sys of theextendr project, with sections liftedfrom there, in addition to new code.

Use of this package is explainedhere, specifically under theSources section.

This library can be installed as usual. It can also built from sourcebut has extra platform-specific dependencies forWindows such asmsys2, typically provided byRtools.

Two components are required to build the library:

1. R: It needs to be installed andavailable in the search path. OnWindows, theRtools binariesare also expected to be on the search path.
2. Rust: It isrecommended to installRust usingrustup; search path shouldincludeRust binaries.

OnceR andRust are configured, the library can be easily built:

# macOS & Linuxcargo build# Windowscargo build --target x86_64-pc-windows-gnu

To test the build, runcargo test.

# macOS & Linuxcargotest# Windowscargotest --target x86_64-pc-windows-gnu
