The ":::" operator doesn't work for me with "Ecdat:::Crime" on
either macOS 10.15.3 or Windows 10.
A different but related issue is that "plm::Crime" says "Error:
'Crime' is not an exported object from 'namespace:plm'", even though
"library(plm); data(Crime); Crime" works. I would naively think a user
should be able to compare "Crime" objects documented in different
packages using the "::" and ":::" operators, even if a package
maintainer chooses not to "export" data objects.
What do you think?
Thanks,
Spencer Graves
