Add a ‘datalist’ File to a Source 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, small.size = 1024^2)
Arguments
pkgpath |
The path to a (source) package. |
force |
logical: can an existing ‘data/datalist’ file be over-written? |
small.size |
number: a ‘data/datalist’ file is created only if
the total size of the data files is larger than |
Details
R CMD build will call this function to add a data list to
packages with 1MB or more of file in the ‘data’ directory.
It can also be also helpful to give a ‘data/datalist’ file in packages whose datasets have many dependencies, including loading the packages itself (and maybe others).
