add_datalist: Add a datalist File to a Package

Description

The data() command with no arguments lists all the datasets available via data in attached packages, and to do so a per-package list is installed. Creating that list at install time can be slow for packages with huge datasets, and can be expedited by a supplying data/datalist file.

Usage

add_datalist(pkgpath, force = FALSE)

Arguments

pkgpath

The path to a (source) package.

force

logical: can an existing data/datalist file be over-written?

Details

R CMD build will call this function to add a data list to packages with 1MB or more of data.

It is also helpful to give a data/datalist file in packages whose datasets have many dependencies, including loading the packages itself (and maybe others).
