drat-package: Easy-to-use package repository creation and access

Description Details Author(s) References See Also Examples


The drat package permits user to create and use ad-hoc package repositories. It takes advantage of GitHub accounts and ‘gh-pages’ branches which automatically become web-accessible and can be used to provide a repository. Alternatively, custom repository paths and addresses can be used.


Given a user account on GitHub, say, ‘eddelbuettel’, and a repository ‘drat’, we can infer an top-level repostory URL as such as http://eddelbuettel.github.io/drat by supplying only the username (as the rest is inferred by defaults). This allows us to create easily useable, identifiable and shareable per-user repositories—without the user having to create and administer a webserver anywhere.

Two higher level functions then allow both insertion of (source or binary) packages, as well as addition of a given drat repository to an R session so that package in the repository can be accesses.
