This package provides an easy access to the latest files. The example below selects the highest resolution file, where the coordinate system is the usual lat/long.

Suppose we selected a file to download. Then you can save it to a
local file using the get_content function. It also save a
copy into a cache under your cache folder. The place of this folder is
OS dependent, use rappdirs::user_cache_dir("eudata") to
locate it.
If you do not specify a dest file, the data will be
downloaded into a temporary file. The path to this file is the
body element of the result of the call.
