Per the posting guide linked below:

"If the question relates to a *contributed package* , e.g., one downloaded
from CRAN, try contacting the package maintainer first. You can also use
find("functionname") and packageDescription("packagename") to find this
information. *Only* send such questions to R-help or R-devel if you get no
reply or need further assistance. This applies to both requests for help
and to bug reports."

So I believe that you should try to contact the maintainer for your
question first. You may get lucky here, of course, but your query seems
rather too technical to expect a useful response on R-Help.
