renviron_d {startup}

Load .Renviron.d and .Rprofile.d directories during the R startup process

Description

Initiates R using all files under ‘.Renviron.d/’ and / or ‘.Rprofile.d/’ directories (or in subdirectories thereof).

Usage

renviron_d(
  sibling = FALSE,
  all = FALSE,
  unload = FALSE,
  skip = NA,
  dryrun = NA,
  debug = NA,
  paths = NULL
)

rprofile_d(
  sibling = FALSE,
  all = FALSE,
  check = NA,
  unload = FALSE,
  skip = NA,
  on_error = c("error", "warning", "immediate.warning", "message", "ignore"),
  dryrun = NA,
  debug = NA,
  paths = NULL
)

startup(
  sibling = FALSE,
  all = FALSE,
  on_error = c("error", "warning", "immediate.warning", "message", "ignore"),
  keep = c("options"),
  check = NA,
  unload = TRUE,
  skip = NA,
  encoding = getOption("encoding"),
  dryrun = NA,
  debug = dryrun
)

Arguments

sibling

If TRUE, then only ‘.Renviron.d/’ and ‘.Rprofile.d/’ directories with a sibling ‘.Renviron’ and ‘.Rprofile’ in the same location will be considered.

all

If TRUE, then all ‘.Renviron.d/’ and ‘.Rprofile.d/’ directories found on the R startup search path are processed, otherwise only the first ones found.

unload

If TRUE, then the package is unloaded afterward, otherwise not.

skip

If TRUE, startup directories will be skipped. If NA, they will be skipped if command-line options --vanilla, --no-init-file, and / or --no-environ were specified.

dryrun

If TRUE, everything is done except the processing of the startup files.

debug

If TRUE, debug messages are outputted, otherwise not.

paths

(internal) character vector of directories.

check

If TRUE, then the content of startup files are validated.

on_error

Action taken when an error is detected when sourcing an Rprofile file. It is not possible to detect error in Renviron files; they are always ignored with a message that cannot be captured.

keep

Specify what information should remain after this function complete. The default is to keep ⁠startup.session.*⁠ options as recorded by startup_session_options().

encoding

The encodingto use when parsing the R startup files. See base::parse() for more details.

Details

The above is done in addition the ‘.Renviron’ and ‘.Rprofile’ files that are supported by the built-in startup process of R.

Functions

• renviron_d(): Initiate using ‘.Renviron.d/’ files

• rprofile_d(): Initiate using ‘.Rprofile.d/’ files

• startup(): renviron_d() followed by rprofile_d() and then the package is unloaded

User-specific installation

In order for ‘.Rprofile.d’ and ‘.Renviron.d’ directories to be included during the R startup process, a user needs to add startup::startup() to ‘~/.Rprofile’. Adding this can also be done by calling install() once.

Site-wide installation

An alternative to having each user add startup::startup() in their own ‘~/.Rprofile’ file, is to add it to the site-wide ‘Rprofile.site’ file (see ?Startup). The advantage of such a site-wide installation, is that the users do not have to have a ‘.Rprofile’ file for ‘.Rprofile.d’ and ‘.Renviron.d’ directories to work. For this to work for all users automatically, the startup package should also be installed in the site-wide library.

Examples

## Not run: 
# The most common way to use the package is to add
# the following call to the ~/.Rprofile file.
startup::startup()

# To process ~/.Renviron.d/ files, and then any ./.Renviron.d/ files,
# followed by  ~/.Rprofile.d/ files, and then any ./.Rprofile.d/ files,
# add the following call to the ~/.Rprofile file.
startup::startup(all = TRUE)

# For finer control of on exactly what files are used
# functions renviron_d() and rprofile_d() are also available:

# Initiate first .Renviron.d/ found on search path
startup::renviron_d()

# Initiate all .Rprofile.d/ directories found on the startup search path
startup::rprofile_d(all = TRUE)

## End(Not run)
