I thought your question had sufficient detail for at least a reasonable guess at an answer. When I first started using R I also thought that the gam function would come from the gam package. It would certainly have been better to provide a full question (starting with a library call to you package, creating a dataset, quite possibly using one from the package help files,  and running code with complete text for all errors),  but this was a case where I thought the source of the problem was clear. I'm sure your next question will be more complete and in plain text.

Best;

David,
