Jetpack
- Lightweight - adds just three files to your project
- Designed for reproducibility - thanks to renv, no more global installs!
- Works from both R and the command line
Inspired by Yarn, Bundler, and Pipenv
Installation
Install Jetpack
install.packages("jetpack")
How It Works
Jetpack uses the DESCRIPTION
file to store your project dependencies. It stores the specific version of each package in renv.lock
. This makes it possible to have a reproducible environment. You can edit dependencies in the DESCRIPTION
file directly, but Jetpack provides functions to help with this.
Getting Started
Open a project and run:
jetpack::init()
Commands
Install
Install packages for a project
jetpack::install()
This ensures all the right versions are installed locally. As dependencies change, collaborators should run this command to stay synced.
Be sure to prefix commands with
jetpack::
. Jetpack isnβt installed in your virtual environment, solibrary(jetpack)
wonβt work.
Add
Add a package
jetpack::add("randomForest")
Add multiple packages
jetpack::add(c("randomForest", "DBI"))
Add a specific version
jetpack::add("[email protected]")
Add from GitHub or another remote source
jetpack::add("plyr", remote="hadley/plyr")
Supports these remotes
Add from a specific tag, branch, or commit
jetpack::add("plyr", remote="hadley/[email protected]")
Add from a local source
jetpack::add("plyr", remote="local::/path/to/plyr")
The local directory must have the same name as the package
Update
Update a package
jetpack::update("randomForest")
For local packages, run this anytime the package code is changed
Update multiple packages
jetpack::update(c("randomForest", "DBI"))
Update all packages
jetpack::update()
Remove
Remove a package
jetpack::remove("randomForest")
Remove multiple packages
jetpack::remove(c("randomForest", "DBI"))
Remove remotes as well
jetpack::remove("plyr", remote="hadley/plyr")
Check
Check that all dependencies are installed
jetpack::check()
Outdated
Show outdated packages
jetpack::outdated()
Source Control
Be sure to commit the files Jetpack generates to source control.
Bioconductor
For Bioconductor, add the BiocManager package first:
jetpack::add("BiocManager")
Then add other packages:
jetpack::add("Biobase", remote="bioc::release/Biobase")
Deployment
Server
Install Jetpack on the server and run:
jetpack::install(deployment=TRUE)
Docker
Create init.R
with:
install.packages("jetpack")
jetpack::install(deployment=TRUE)
And add it into your Dockerfile
:
FROM r-base
RUN apt-get update && apt-get install -qq -y --no-install-recommends \
libxml2-dev libssl-dev libcurl4-openssl-dev libssh2-1-dev
RUN mkdir -p /app
WORKDIR /app
COPY init.R DESCRIPTION renv.lock ./
RUN Rscript init.R
COPY . .
CMD Rscript app.R
Heroku
For the R buildpack, create init.R
with:
install.packages("jetpack")
jetpack::install(deployment=TRUE)
Alternatively, you can use Docker Deploys on Heroku.
Command Line
Jetpack can also be run from the command line. To install the CLI, run:
jetpack::cli()
On Windows, add
C:\ProgramData\jetpack\bin
to your PATH. See instructions for how to do this.
All the Jetpack commands are now available
jetpack init
jetpack install
jetpack add randomForest
jetpack add [email protected]
jetpack add plyr --remote=hadley/plyr
jetpack update randomForest
jetpack remove DBI
jetpack check
jetpack outdated
You can also use it to manage global packages
jetpack global add randomForest
jetpack global update DBI
jetpack global update
jetpack global remove plyr
jetpack global list
jetpack global outdated
You can even use it to update itself
jetpack global update jetpack

jetpack help
Upgrading
To upgrade, rerun the installation instructions.
0.5.0
Jetpack 0.5.0 uses renv instead of Packrat. To upgrade a project:
- Run
jetpack::migrate()
- Delete
packrat.lock
- Run
jetpack::install()
0.4.0
Jetpack 0.4.0 greatly reduces the number of dependencies. As part of this, the info
and search
commands have been removed.
0.3.0
Jetpack 0.3.0 greatly reduces the number of files in your projects. To upgrade a project:
- Move
packrat/packrat.lock
topackrat.lock
- Delete the
packrat
directory - Delete
.Rbuildignore
and.gitignore
if they only contain Packrat references - Replace all Jetpack and Packrat code in your
.Rprofile
with:
if (requireNamespace("jetpack", quietly=TRUE)) {
jetpack::load()
} else {
message("Install Jetpack to use a virtual environment for this project")
}
- Open R and run:
jetpack::install()

cd jetpack
In R, do:
install.packages("devtools")
devtools::install_deps(dependencies=TRUE)
devtools::test()
To test a single file, use:
devtools::install() # to use latest updates
devtools::test_active_file("tests/testthat/test-jetpack.R")
