Packages have specific structure and tools built to enforce some documentation and testing; these lead to a better final product but create a higher hurdle for package creation, especially the first time when the conventions are being learned. This talk will walk through all the steps of creating a package including fulfilling the documentation and testing requirements (and options), resulting in a package that can be distributed and installed by others. A combination of standard tools as well as those provided by the devtools and roxygen2 packages will be used.</span></p> </div> <h3>Links</h3> <ul> <li><a class="url u-url" href="http://www.meetup.com/portland-r-user-group/events/76891132/">Website</a></li> </ul> </div>
