metacran — Tooling around CRAN R packages

metacran is a collection of projects to allow better tooling around CRAN R packages. It contains a number of projects. The following ones are stably working and can be considered beta software:

• Web site to browse and search CRAN packages.
• CRAN @ github, read-only mirror of CRAN at github.
• crandb, a database of CRAN R packages, with an HTTP API, and an R package to access it from R.
• CRAN package search, based on crandb. This is now included in the Metacran web site at http://www.r-pkg.org.
• seer, R package to search for CRAN packages.
• r-builder Scripts to use Travis or another CI to build and check R packages with various R versions, including R-devel.
• cranlogs A database and R package for daily R package download counts from the RStudio CRAN mirror.
• rversions An R package to query R versions and their release dates from the R project SVN repository.

metacran also contains some experimental packages and tools:

• spareserver R package to fallback to another web server if the main one is not responding.
• cranny packer templates to build the metacran servers.
