It is vectorised so you can install multiple packages with a single command. You do not need to have the git2r package, or an external git client installed.

Usage

install_git(
  url,
  subdir = NULL,
  ref = NULL,
  branch = NULL,
  credentials = git_credentials(),
  git = c("auto", "git2r", "external"),
  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

url

Location of package. The url should point to a public or private repository.

subdir

A sub-directory within a git repository that may contain the package we are interested in installing.

ref

Name of branch, tag or SHA reference to use, if not HEAD.

branch

Deprecated, synonym for ref.

credentials

A git2r credentials object passed through to clone. Supplying this argument implies using git2r with git.

git

Whether to use the git2r package, or an external git client via system. Default is git2r if it is installed, otherwise an external git installation.

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 "ask" prompts the user for which out of date packages to upgrade.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 you need to set git credentials for use in the Remotes field you can do so by placing the credentials in the remotes.git_credentials global option.

Examples

if (FALSE) {
install_git("https://github.com/hadley/stringr.git")
install_git("https://github.com/hadley/stringr.git", ref = "stringr-0.2")
}
