usethis (version 1.4.0)

use_description: Create or modify a DESCRIPTION file

Description

usethis consults the following sources, in this order, to set DESCRIPTION fields:

• fields argument of create_package() or use_description().

• getOption("usethis.description") or getOption("devtools.desc"). The devtools option is consulted only for backwards compatibility and it's recommended to switch to an option named "usethis.description".

• Defaults built into usethis.

The fields discovered via options or the usethis package can be viewed with use_description_defaults().

If you create a lot of packages, consider storing personalized defaults as a named list in an option named "usethis.description". Here's an example of code to include in .Rprofile:

options(
  usethis.description = list(
    `Authors@R` = 'person("Jane", "Doe", email = "[e-mail]", role = c("aut", "cre"))',
    License = "MIT + file LICENSE",
    Language: es
  )
)

Usage

use_description(fields = NULL)
use_description_defaults()

Arguments

fields

A named list of fields to add to DESCRIPTION, potentially overriding default values. See use_description() for how you can set personalized defaults using package options
