Earlier this year, I created a GitHub repository to store material for the one-day introductory workshop I presented at the RPM in Washington, DC. I'm doing that again at the RPM in Dallas next year. I've changed the name of the repository to something a bit more generic (it had been called "RPM2014").
I'm also going through the process of moving from .Rnw to .Rmd. This will support more output formats. The one I'm partial to at the moment is using the "Slidy" format for HTML5. Slidy is great because you can zoom in and out. I learned quickly that attendees had trouble reading the source code I'd put on a slide because the font was too small.
Feel free to fork the repository, submit pull requests, etc. It's a bit of a shambles at the moment, but should be clean fairly soon. Note that one of the branches is for a GitHub pages website with instructions and downloads for workshop attendees.
