Export files as Python or R package

If you organize the files in a project as an installable package, then you can choose to export it as such. When another project imports this project, Domino will automatically install the package at runtime, making it available to your code.

  1. Configure your project to export files.

  2. From Code Package, select the language.

    export files packages

The following describes the language-specific pattern required for any package.

See the official manual for an in-depth guide to writing R extensions.

In summary, each R package requires:

  • A directory called R/ with code files.

  • A directory called man/ with documentation files.

  • A file named DESCRIPTION, with each line following the pattern link:key>: <value[]. The required keys include:

    • Package

    • Version (for example, 0.1)

    • Title

    • Description

    • Author

    • Maintainer (a name followed by an email address in angle brackets, for example, Sample Maintainer <maintainer@example.com>)

    • License

  • A file named NAMESPACE that describes the namespace of the package. If you don’t know what to put here, exportPattern( "." ) works in many cases.
