Installs metabodecon's Rust backend mdrb from R-Universe.
![[Experimental]](figures/lifecycle-experimental.svg)
The Rust backend is entirely optional; metabodecon's pure-R backend is the
default and always available. R-Universe provides pre-built mdrb binaries
only for the two most recent R releases. On those, installation is a
plain binary download and requires no toolchain. On older R versions
(still >= 4.2) or platforms without a pre-built binary, mdrb must be
built from source, which requires a Rust toolchain (cargo and rustc
>= 1.80; check with check_mdrb_deps()). If automatic
installation fails, install_mdrb() does not error: it prints guidance and
returns FALSE, pointing to https://github.com/spang-lab/mdrb for manual
installation.
Arguments
- ask
Whether to ask for confirmation before attempting installation. Default is TRUE.
- ...
Additional arguments to pass to
utils::install.packages()when attempting installation of mdrb.
Value
Invisibly returns TRUE if mdrb is available after the call, else
FALSE. Called mainly for the side effect of installing the Rust backend.
Examples
if (interactive()) try(install_mdrb())
