Devtools version 1.9 supports package dependency installation for packages not yet in a standard package repository such as CRAN or Bioconductor.
You can mark any regular dependency defined in the Depends
, Imports
,
Suggests
or Enhances
fields as being installed from a remote location by
adding the remote location to Remotes
in your DESCRIPTION
file. This will
cause devtools to download and install them prior to installing your package (so they won't be installed from CRAN).
The remote dependencies specified in Remotes
should be described in the following form.
Remotes: [type::]<Repository>, [type2::]<Repository2>
The type
is an optional parameter. If the type is missing the default is
to install from GitHub. Additional remote dependencies should be separated by
commas, just like normal dependencies elsewhere in the DESCRIPTION
file.
Because github is the most commonly used unofficial package distribution in R, it's the default:
Remotes: hadley/testthat
You can also specify a specific hash, tag, or pull request (using the same syntax as install_github()
if you want a particular commit. Otherwise the latest commit on the master branch is used.
Remotes: hadley/httr@v0.4,
klutometis/roxygen#142,
hadley/testthat@c67018fa4970
A type of 'github' can be specified, but is not required
Remotes: github::hadley/ggplot2
All of the currently supported install sources are available, see the 'See
Also' section in ?install
for a complete list.
# Git Remotes: git::https://github.com/hadley/ggplot2.git # Bitbucket Remotes: bitbucket::sulab/mygene.r@default, dannavarro/lsr-package # SVN Remotes: svn::https://github.com/hadley/stringr # URL Remotes: url::https://github.com/hadley/stringr/archive/master.zip # Local Remotes: local::/pkgs/testthat # Gitorious Remotes: gitorious::r-mpc-package/r-mpc-package
When you submit your package to CRAN, all of its dependencies must also be available on CRAN. For this reason, release()
will warn you if you try to release a package with a Remotes
field.
