I recommend you revert all the changes you made that are documented in
the package NEWS, and at minimum follow Ivan's advice to use
exportPattern("^[^\\.]") instead of exportPattern("."). It would be
even better to follow the advice in Writing R Extensions and list each
exported object individually.

That section of Writing R Extensions specifically says not to do what you did.
Beware of patterns which include names starting with a period: some
of these are internal-only variables and should never be exported,
e.g. ‘.__S3MethodsTable__.’ (and loading excludes known cases).
Duncan pointed out that '.__global__' is an internal-only variable
created by globalVariables(), which means it should never be exported
by a package. Imagine the number of conflicts there would be if every
package that used globalVariables() exported the '.__global__'
object... there would probably be thousands, yikes!
It's possible that future versions of 'R CMD check' will error if
there are any incorrectly exported internal variables (like
'.__global__'), which would cause your package to fail.
Best,
Josh
