This serves as a simple index page for some information about remote data available for download in {peacesciencer}. CRAN has a size requirement—5 MB for the whole package—that can be restrictive for a package that aims to do as many things as {peacesciencer}. This will concern some data sets of interest for users. These are always the largest files in an R package.

How {peacesciencer} Informs You About These Data for Download

First, open R and load {peacesciencer} into the session. If you are greeted with a message about extra data for download, it’s because you just downloaded/updated the package and don’t have these data right now. A simple call of download_extdata() will accomplish this.
