stan_cmdstan_path {instantiate}

Path to CmdStan for instantiate

Description

Return the directory path to CmdStan that the instantiate package uses.

Usage

stan_cmdstan_path(cmdstan_install = Sys.getenv("CMDSTAN_INSTALL", unset = ""))

Arguments

cmdstan_install

Character of length 1, how to look for an installed copy of CmdStan. See https://wlandau.github.io/instantiate/ for details. Choices:

1. "" (default): look at the original value that the CMDSTAN_INSTALL environment variable contained when instantiate at the time when it was installed. If it was "implicit" or "fixed", then choose the corresponding option below. Otherwise, default to "implicit".

2. "implicit": Let the cmdstanr::cmdstan_path() decide where to look for CmdStan. As explained in the cmdstanr documentation, the output of cmdstanr::cmdstan_path() depends on the current value of the CMDSTAN environment variable. The cmdstanr package must be installed. If it is not installed, then stan_cmdstan_path() returns the empty string "".

3. "fixed": Use the path to CmdStan that was originally contained in Sys.getenv("CMDSTAN") at the time when instantiate was installed.

Value

Character of length 1, directory path to CmdStan. The path may or may not exist. Returns the empty string "" if the path cannot be determined.
