I am eager to learn how to incorporate data examples as comments written above the functions, such as:
##\' @examples ##\' ## Set working directory... ##\'
Please look at CRAN packages that include data and copy their approach. I just added data to a at-work-only package a few weeks back and it just works...
For what it is worth, the manual has a section 1.1.5 Data in packages which explains it.
