packrat-resources: Paths to Packrat Resources

In rstudio/packrat: A Dependency Management System for Projects and their R Package Dependencies

Paths to Packrat Resources

Description

These functions provide a mechanism for retrieving the paths to Packrat resource directories. Each of these directories can be overridden by setting either an environment variable, or an R option.

Usage

project_dir(project = NULL)

src_dir(project = NULL)

lib_dir(project = NULL)

bundles_dir(project = NULL)

Arguments

project

The project directory.

Project Directory

project_dir() is special – the R_PACKRAT_PROJECT_DIR environment variable is set and unset by on and off, respectively, and generally should not be overridden by the user.

Directory Resolution

The following table shows the order in which resource directories are discovered (from left to right). The first non-empty result is used.

API	Environment Variable	R Option	Default Value
project_dir()	R_PACKRAT_PROJECT_DIR	packrat.project.dir	getwd()
src_dir()	R_PACKRAT_SRC_DIR	packrat.src.dir	"packrat/src"
lib_dir()	R_PACKRAT_LIB_DIR	packrat.lib.dir	"packrat/lib"
bundles_dir()	R_PACKRAT_BUNDLES_DIR	packrat.bundles.dir	"packrat/bundles"
(none)	R_PACKRAT_LIB_R_DIR	packrat.lib-r.dir	"packrat/lib-R"
(none)	R_PACKRAT_LIB_EXT_DIR	packrat.lib-ext.dir	"packrat/lib-ext"
