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

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

if (FALSE) { # \dontrun{
# 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)
} # }
