rapport package comes with bunch of helper functions that make your template writing and report creation easier, although most of these helpers were migrated to the rapportools package.

Please load the rapportools package if you would use any of the below functions in the .GlobalEnv, or simply add rapportools to the required packages section in your template file. That latter is a lot cleaner solution.
