Attempts to install a package directly from GitHub.

This function is vectorised on repo so you can install multiple packages in a single command.

Usage

install_github(
  repo,
  ref = "HEAD",
  subdir = NULL,
  auth_token = github_pat(quiet),
  host = "api.github.com",
  dependencies = NA,
  upgrade = c("default", "ask", "always", "never"),
  force = FALSE,
  quiet = FALSE,
  build = TRUE,
  build_opts = c("--no-resave-data", "--no-manual", "--no-build-vignettes"),
  build_manual = FALSE,
  build_vignettes = FALSE,
  repos = getOption("repos"),
  type = getOption("pkgType"),
  ...
)

Arguments

repo

Repository address in the format username/repo[/subdir][@ref|#pull|@*release]. Alternatively, you can specify subdir and/or ref using the respective parameters (see below); if both are specified, the values in repo take precedence.

ref

Desired git reference. Could be a commit, tag, or branch name, or a call to github_pull() or github_release(). Defaults to "HEAD", which means the default branch on GitHub and for git remotes. See setting-the-default-branch for more details.

subdir

Subdirectory within repo that contains the R package.

auth_token

To install from a private repo, generate a personal access token (PAT) with at least repo scope in https://github.com/settings/tokens and supply to this argument. This is safer than using a password because you can easily delete a PAT without affecting any others. Defaults to the GITHUB_PAT environment variable.

host

GitHub API host to use. Override with your GitHub enterprise hostname, for example, "github.hostname.com/api/v3".

dependencies

Which dependencies do you want to check? Can be a character vector (selecting from "Depends", "Imports", "LinkingTo", "Suggests", or "Enhances"), or a logical vector.

TRUE is shorthand for "Depends", "Imports", "LinkingTo" and "Suggests". NA is shorthand for "Depends", "Imports" and "LinkingTo" and is the default. FALSE is shorthand for no dependencies (i.e. just check this package, not its dependencies).

The value "soft" means the same as TRUE, "hard" means the same as NA.

You can also specify dependencies from one or more additional fields, common ones include:

• Config/Needs/website - for dependencies used in building the pkgdown site.

• Config/Needs/coverage for dependencies used in calculating test coverage.

upgrade

Should package dependencies be upgraded? One of "default", "ask", "always", or "never". "default" respects the value of the R_REMOTES_UPGRADE environment variable if set, and falls back to "ask" if unset. "ask" prompts the user for which out of date packages to upgrade. For non-interactive sessions "ask" is equivalent to "always". TRUE and FALSE are also accepted and correspond to "always" and "never" respectively.

force

Force installation, even if the remote state has not changed since the previous install.

quiet

If TRUE, suppress output.

build

If TRUE build the package before installing.

build_opts

Options to pass to R CMD build, only used when build is TRUE.

build_manual

If FALSE, don't build PDF manual ('--no-manual').

build_vignettes

If FALSE, don't build package vignettes ('--no-build-vignettes').

repos

A character vector giving repositories to use.

type

Type of package to update.

...

Other arguments passed on to utils::install.packages().

Details

If the repository uses submodules a command-line git client is required to clone the submodules.
