Install the packages a manual's modules need

The modules a manual documents declare their own reqdPkgs, which the manual must install before it can knit their chapters. Call this after the manual's own dependencies are in place – typically right after remotes::install_deps(), which is what installs this package.

Usage

installModulePkgs(
  modulePath = "modules",
  modules = NULL,
  dependencies = TRUE,
  install = TRUE
)

Arguments

modulePath

directory holding the module directories.

modules

names of the modules to resolve. Defaults to every directory under modulePath.

dependencies

whether to expand each module package's own dependencies with Require::pkgDep2() before installing. FALSE installs only the packages the modules name.

install

whether to install. FALSE resolves the package list and returns it without installing anything, which is useful for seeing what a manual's modules ask for.

Value

the packages, invisibly.

Details

The package list is deliberately assigned before being installed rather than piped. Require::Install() names its first parameter packages and calls substitute() on it, so a piped expression resolves to the literal string "packages" and the installer is asked for a package by that name. Require::pkgDep2() also returns a named list, which Install() wants flattened.
