Package 'envsetup' reference manual

Title:	Support the Setup of the R Environment for Clinical Trial Programming Workflows
Description:	The purpose of this package is to support the setup the R environment. The two main features are 'autos', to automatically source files and/or directories into your environment, and 'paths' to consistently set path objects across projects for input and output. Both are implemented using a configuration file to allow easy, custom configurations that can be used for multiple or all projects.

Build directory structure from a configuration file

Description

Build directory structure from a configuration file

Usage

build_from_config(config, root = NULL)
build_from_config(config, root = NULL)

Arguments

`config`	configuration object from config::get() containing paths#'
`root`	root directory to build from. Leave as NULL if using absolute paths. Set to working directory if using relative paths.

Value

Called for its side-effects. The directories build print as a tree-like format from fs::dir_tree().

Examples

tmpdir <- tempdir()

hierarchy <- "default:
  paths:
    data: !expr list(DEV = '/demo/DEV/username/project1/data',
                     PROD = '/demo/PROD/project1/data')

Wrapper around library to place packages after any current autos

Description

Autos need to immediately follow the global environment. This wrapper around base::library() will position any attached packages in the earliest position on the search path currently occupied by a package environment, guaranteeing newly loaded packages appear before previously loaded packages but after any currently attached non-packages.

Arguments

`...`	pass directly through to base::library
`pos`	see base::library. NULL (the default) is taken to mean the earliest position of a package environment within the current search path. If non-null, underlying behavior of base::library is respected.

Value

returns (invisibly) the list of attached packages

Examples

# Simple example
library(purrr)

# Illustrative example to show that autos will always remain above attached libraries

print(tmpdir)

# account for windows

Read path

Description

Check each environment for the file and return the path to the first.

Usage

read_path(
  lib,
  filename,
  full.path = TRUE,
  envsetup_environ = Sys.getenv("ENVSETUP_ENVIRON")
)
read_path(
  lib,
  filename,
  full.path = TRUE,
  envsetup_environ = Sys.getenv("ENVSETUP_ENVIRON")
)

Arguments

`lib`	object containing the paths for all environments of a directory
`filename`	name of the file you would like to read
`full.path`	logical to return the path including the file name
`envsetup_environ`	name of the environment you would like to read the file from; default values comes from the value in the system variable ENVSETUP_ENVIRON which can be set by Sys.setenv(ENVSETUP_ENVIRON = "environment name")

Details

The environments searched depends on the current environment. For example, if your workflow contains a development (dev) area and production area (prod), and the code is executing in the dev environment, we search dev and prod. If in prod, we only search prod.

Value

string containing the path of the first directory the file is found

Examples

tmpdir <- tempdir()

# account for windows
if (Sys.info()['sysname'] == "Windows") {
  tmpdir <- gsub("\\", "\\\\", tmpdir, fixed = TRUE)

Retrieve a file path from an envsetup object containing paths

Description

Paths will be filtered to produce the lowest available level from a hierarchy of paths based on envsetup_environ

Usage

write_path(
  lib,
  filename = NULL,
  envsetup_environ = Sys.getenv("ENVSETUP_ENVIRON")
)
write_path(
  lib,
  filename = NULL,
  envsetup_environ = Sys.getenv("ENVSETUP_ENVIRON")
)

Arguments

`lib`	Object containing the paths for all environments of a directory
`filename`	Name of the file you would like to write
`envsetup_environ`	Name of the environment to which you would like to write. Defaults to the ENVSETUP_ENVIRON environment variable

Value

path to write

Examples

tmpdir <- tempdir()

# account for windows
if (Sys.info()['sysname'] == "Windows") {
  tmpdir <- gsub("\\", "\\\\", tmpdir, fixed = TRUE)
}

# add config for just the data location

# write config file to temp directory
writeLines(hierarchy, file.path(tmpdir, "hierarchy.yml"))

config <- config::get(file = file.path(tmpdir, "hierarchy.yml"))

# build folder structure from config
build_from_config(config)

# setup environment based on config

# find location to write mtcars.rds
