Get dependencies for a Stan function

Returns all Stan functions that the specified function depends on, in topological order (dependencies before the functions that use them).

Usage

pcd_stan_function_deps(
  function_name,
  stan_path = primarycensored::pcd_stan_path()
)

Arguments

function_name

Character string, the name of the Stan function.

stan_path

Character string specifying the path to the directory containing Stan files. Defaults to the Stan path of the primarycensored package.

Value

A character vector of function names that the specified function depends on, ordered so that dependencies come before functions that use them. The requested function itself is included as the last element.
