usethis is a workflow package: it automates repetitive tasks that arise during project setup and development, both for R packages and non-package projects.


Install the released version of usethis from CRAN:


Or install the development version from GitHub with:

# install.packages("devtools")


Most use_*() functions operate on the active project: literally, a directory on your computer. If you’ve just used usethis to create a new package or project, that will be the active project. Otherwise, usethis verifies that current working directory is or is below a valid project directory and that becomes the active project. Use proj_get() or proj_sitrep() to manually query the project and read more in the docs.

A few usethis functions have no strong connections to projects and will expect you to provide a path.

usethis is quite chatty, explaining what it’s doing and assigning you tasks. indicates something usethis has done for you. indicates that you’ll need to do some work yourself.

Below is a quick look at how usethis can help to set up a package. But remember, many usethis functions are also applicable to analytical projects that are not packages.


# Create a new package -------------------------------------------------
tmp <- file.path(tempdir(), "mypkg")
#> ✔ Setting active project to '/private/var/folders/vr/gzrbtprx6ybg85y5pvwm1ct40000gn/T/RtmpGwzXO5/mypkg'
#> ✔ Creating 'R/'
#> ✔ Creating 'man/'
#> ✔ Writing 'DESCRIPTION'
#> ✔ Writing 'NAMESPACE'

# Modify the description ----------------------------------------------
use_mit_license("My Name")
#> ✔ Setting License field in DESCRIPTION to 'MIT + file LICENSE'
#> ✔ Writing ''
#> ✔ Adding '^LICENSE\\.md$' to '.Rbuildignore'
#> ✔ Writing 'LICENSE'

use_package("MASS", "Suggests")
#> ✔ Adding 'MASS' to Suggests field in DESCRIPTION
#> ● Use `requireNamespace("MASS", quietly = TRUE)` to test if package is installed
#> ● Then use `MASS::fun()` to refer to functions.

#> ✔ Adding 'callr' to Imports field in DESCRIPTION
#> ✔ Adding 'r-lib/callr' to Remotes field in DESCRIPTION

# Set up various packages ---------------------------------------------
#> ✔ Setting Roxygen field in DESCRIPTION to 'list(markdown = TRUE)'
#> ✔ Setting RoxygenNote field in DESCRIPTION to '6.1.0'
#> ● Run `devtools::document()`

#> ✔ Adding 'Rcpp' to LinkingTo field in DESCRIPTION
#> ✔ Adding 'Rcpp' to Imports field in DESCRIPTION
#> ✔ Creating 'src/'
#> ✔ Adding '*.o', '*.so', '*.dll' to 'src/.gitignore'
#> ● Include the following roxygen tags somewhere in your package
#>   #' @useDynLib mypkg, .registration = TRUE
#>   #' @importFrom Rcpp sourceCpp
#>   NULL
#> ● Run `devtools::document()`

#> ✔ Creating 'revdep/'
#> ✔ Adding '^revdep$' to '.Rbuildignore'
#> ✔ Adding 'checks', 'library', 'checks.noindex', 'library.noindex', 'data.sqlite', '*.html' to 'revdep/.gitignore'
#> ✔ Writing 'revdep/email.yml'
#> ● Run checks with `revdepcheck::revdep_check(num_workers = 4)`

# Set up other files -------------------------------------------------
#> ✔ Writing ''

#> ✔ Writing ''

#> ✔ Adding 'testthat' to Suggests field in DESCRIPTION
#> ✔ Creating 'tests/testthat/'
#> ✔ Writing 'tests/testthat.R'
#> ✔ Writing 'tests/testthat/test-my-test.R'

x <- 1
y <- 2
use_data(x, y)
#> ✔ Creating 'data/'
#> ✔ Saving 'x', 'y' to 'data/x.rda', 'data/y.rda'

# Use git ------------------------------------------------------------
#> ✔ Initialising Git repo
#> ✔ Adding '.Rhistory', '.RData', '.Rproj.user' to '.gitignore'
