Very simple use of sessioninfo::session_diff to get directly at package/version differences between sessions
The session_diff() function produces attractive reports based on elementary information about session characteristics. This package extracts one form of elementary information and presents it for further analysis.
The idea is very simple. Identical sessions cannot be distinguished.
> si = sessioninfo::session_info()
> sessdiff(si, si)
$xonly
character(0)
$yonly
character(0)If one of the sessions has an additional package loaded, we find it:
> requireNamespace("parody") # unlikely to be loaded
> si2 = sessioninfo::session_info()
> sessdiff(si, si2)
$xonly
character(0)
$yonly
