folders (version 0.1.0)

get_folders: Get Folders

Description

Return a named list of standard folder names. Save a config file if missing.

Usage

get_folders(conf_file = NULL, conf_name = Sys.getenv("R_CONFIG_NAME"))

Value

(list) The named folders for a standard file structure, will be returned as a list.

Arguments

conf_file

(character) Configuration file to read/write. See: config::get(). (Default: NULL)

conf_name

(character) Name of configuration to read. See: config::get(). (Default: Sys.getenv("R_CONFIG_NAME"))

Details

The list of folders can be used to create any which are missing or to refer to a folder path by name to avoid hardcoding paths in scripts. You can refer to folders in this way to avoid the use of setwd() in scripts.

Ideally the folder paths will be subfolders relative to the parent folder and will be standard names used in several projects for consistency.

If there is a configuration file, then it will be read with config::get(). Otherwise a built-in default list will be returned. If you want to use a list from a non-default section of the configuration file, set the name of the section with the "conf_name" parameter.

Examples

folders <- get_folders()                 # Configuration file not used
conf_file <- tempfile("folders.yml")     # Using tempfile() for testing only
folders <- get_folders(conf_file)
folders <- get_folders(conf_file, conf_name = "custom")
Sys.setenv(R_CONFIG_NAME = "custom")
folders <- get_folders(conf_file)
