Deletes all files downloaded and cached by the obr package. The next function call will re-download fresh data from the OBR website.
Details
Files are cached in tools::R_user_dir("obr", "cache"), or the
directory set with options(obr.cache_dir = ). Each edition of a
publication is cached separately, and a cached file is used for 7 days
before it is downloaded again; set options(obr.cache_ttl = ) to a
number of hours to change this. If a re-download fails, the expired
copy is used with a warning.
Examples
# \donttest{
op <- options(obr.cache_dir = tempdir())

#> Warning: cannot remove file '/tmp/RtmpIG70RJ/downlit', reason 'Directory not empty'
