Install R Packages from remote or local repositories, including GitHub, GitLab, Bitbucket, and Bioconductor
Download and install R packages stored in GitHub, GitLab, Bitbucket,
Bioconductor, or plain subversion or git repositories. This package is a
lightweight replacement of the
install_* functions in
devtools. Indeed most of the code
was copied over from
- Install packages with their dependencies.
- Install from GitHub, GitLab, Bitbucket.
- Install from git and subversion repositories.
- Install from local files or URLs.
- Install the dependencies of a local package tree.
- Install specific package versions from CRAN.
- Supports Bioconductor packages.
- Supports the

- Can install itself from GitHub (see below).
- Does not depend on other R packages.
- Does not contain compiled code, so no compiler is needed.
- Does not need any external software (for most of the functionality at least).
Install the released version of remotes from CRAN:
Note that most of the examples here use GitHub. See below for other supported repository types.
To install the latest version of a package in the default branch from
GitHub, you can use the
user/repo form. Note that
user can also be
If the R package is inside a subdirectory of the root directory, then give this subdirectory as well:
# build = FALSE because of some specificities of XGBoost package install_github("dmlc/xgboost/R-package", build = FALSE)
To install a certain branch or commit or tag, append it to the repo
name, after an
To install the latest release, append
@*release to the repo name:
To install a pull request, append
# and the id (an integer number) of
the pull request to the repo name:
Dependencies are automatically installed from CRAN. By default, outdated dependencies are automatically upgraded. In interactive sessions you can select a subset of the dependencies to upgrade.
Dependencies on GitHub
It is also possible to install dependencies from GitHub or other
supported repositories. For this you need to add a
Remotes field to
DESCRIPTION file. Its format is:
Remotes: [remote::]repo_spec, [remote::]repo_spec, ...
repo_spec is any repository specification the corresponding
install_() function can handle. If
remote:: is missing,
is assumed. Other possible values:

This is a way to specify dependencies from non-CRAN package
repositories. See the Writing R
manual for details.
Bioconductor packages are automatically detected and their dependencies are installed from Bioconductor.
Currently supported remote types
- GitHub repositories via
- Bitbucket repositories via
- Generic git repositories via
install_git. They need either a system git installation, or the git2r R package.
- Local directories or package archive files via
- Remote package archive files via
- Packages in subversion repositories via
install_svn. They need a system subversion installation.
- Specific package versions from CRAN or other CRAN-like repositories
install_version. This includes outdated and archived packages as well.
- All dependencies of a package in a local directory via
- For R older than 3.2, the curl package is required as remotes falls
curl::curl_downloadin that case
- For R newer than 3.3, default
download.file()method is used. (
method = "auto")
- For in between versions,
method = "wininet"is used on windows OS
method = "libcurl"is used on other OS, if available.
help("download.file") for information on these methods and for
setting proxies if needed.
remotes will use the curl, git2r and pkgbuild packages if they are installed to provide faster implementations for some aspects of the install process. However if you are using remotes to install or update these packages (or their reverse dependencies) using them during installation may fail (particularly on Windows).
If you set the environment variable
Sys.setenv(R_REMOTES_STANDALONE="true")) you can force remotes to
operate in standalone mode and use only its internal R implementations.
This will allow successful installation of these packages.
remotes uses the following standard R options, see
?options for their
download.file.methodfor the default download method. See
pkgTypefor the package type (source or binary, see manual) to install, download or look up dependencies for.
reposfor the locations of the user’s standard CRAN(-like) repositories.
It also uses some remotes specific options:
BioC_gitfor the URL of the default Bioconductor git mirror.
BioC_mirrorfor the URL of the Bioconductor mirror.
unzipfor the path of the external
BITBUCKET_PASSWORDenvironment variables are used for the default Bitbucket user name and password, in
GITHUB_PATenvironment variable is used as the default GitHub personal access token for all GitHub API queries.
R_BIOC_MIRRORenvironment variable can be used to specify an alternative Bioconductor mirror. (The
BioC_mirroroption takes precedence over this.)
R_BIOC_VERSIONenvironment variable can be used to force a Bioconductor version.
R_REMOTES_UPGRADEenvironment variable can be used to set a default preferred value for the
upgrade =argument accepted by the various
install_*()functions. For example, you can set
R_REMOTES_UPGRADE="always"to upgrade dependent packages without asking the user.
R_REMOTES_STANDALONE="true"forces remotes to work in standalone mode and avoid loading its optional dependencies (curl, git2 and pkgbuild currently. See “Standalone mode” above.
R_REMOTES_NO_ERRORS_FROM_WARNINGS="false"will cause warning messages during calls to
install.packages()to become errors. Often warning messages are caused by dependencies failing to install.
