   Bug reports on contributed packages should be sent first to the package    maintainer, and only submitted to the R-bugs repository by package    maintainers, mentioning the package in the subject line.

and you are NOT the listed maintainer.

Do learn to read FAQs before causing unnecessary work for other people (as the R posting guide asks).

Please do as the FAQ asks.
