Well I located the error and it had to do with an existing .RData file that had a print method defined for a class which is part of a package that wasn't loaded. Starting an interactive session, removing the objects of the specialized class from the top-level environment, and re-saving the environment permitted the Rscript to run correctly. I suppose similarly if the script loaded the package it would've run also.
Thanks to all for the emails with suggestions.
