[R-pkg-devel] import 'as' from another package

[Sebastian Meyer]

Yes, indeed, it is confusing. You don't need to file a new bug report, though. There is one already:

https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17179

Please feel free to comment there. This thread could serve as another confirmation. :-)

Best regards,
Sebastian
