Perhaps you should read the posting guide at first (and each R-help 
message contains the footer):

"PLEASE do read the posting guide 
http://www.R-project.org/posting-guide.html and provide commented, 
minimal, self-contained, reproducible code."

It is also a good idea to sign messages with a name, we are quite 
reluctant to answer to robots.

If you had given reproducible code, I suspect some people would be 
volunteering to look at it, perhaps including the authors of those 
functions and the package maintainer who could also be asked (including 
the aforementioned relevant details, of course).

Best,
