\title{
  Add a \file{datalist} File to a Package
}
\description{
  The \code{\link{data}()} command with no arguments lists all the
  datasets available via \code{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 \file{data/datalist} file.
}
\usage{
add_datalist(pkgpath, force = FALSE)
}
\arguments{
  \item{pkgpath}{The path to a (source) package.}

  \item{force}{logical: can an existing \file{data/datalist} file be
    over-written?}
}
\details{
  \command{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 \file{data/datalist} file in packages
  whose datasets have many dependencies, including loading the packages
  itself (and maybe others).
