Add pages above here with various tutorials and session examples using R. These tutorials and/or R sessions could be general presentations of R features, or they could take the form of cookbooks for more specific topics.
If your contribution is a single page, place it in one of the subsections “intros”, “demos” or “cookbooks”. If it is a larger contribution with many pages, create a dedicated subsection in tutorials (like “stats-with-r”, for instance). Use the “snippets” section instead for short documents.
