These are links to a series of talks on using R for basic data management and analysis. The links below are of two flavors. One is HTML files which when you click on them will download, and then you can open them when they are downloaded and view a slide show in your default browser. The other types of files are RMD files, which are R Markdown files, which contain a blend of R code and Markdown code used with RStudio to prepare the slide shows.
