Setup cmdstanr and CmdStan — setup

Checks the C++ toolchain, locates CmdStan, and installs or upgrades CmdStan if needed. Prefer setup_interface() for user-facing setup since it performs argument validation and defaults; setup_cmdstanr() assumes inputs are already checked.

Usage

setup_cmdstanr(quiet, force, reinstall = FALSE, check_updates = TRUE, cores)

Arguments

quiet: Logical. If TRUE, suppresses status messages.
force: Logical. If TRUE, allows installation in non-interactive sessions.
reinstall: Logical. If TRUE, forces re-installation.
check_updates: Logical. If TRUE, checks for CmdStan updates.
cores: Integer. Number of cores to use. Defaults to getOption("mc.cores"). You must set options(mc.cores = ...) or pass cores explicitly.

Value

Returns TRUE invisibly when no install/upgrade is needed. Otherwise, returns NULL invisibly after installation.
