I am in the process of building a series of tutorials on the Data@Reed website. The current set of tutorials address among the most common tasks in R, such as reading in data, creating variables, and creating plots as well as more complicated tasks like creating html tables and interactive graphs.
All of the tutorials are produced in R Markdown and contain code that you can copy and paste into RStudio to replicate the output. For example, my most recent addition “Package RColorBrewer with ggplot2” demonstrates how to change the color scheme of your graphs.
If you have questions about R please stop by my office (ETC 223) or email me at majerus@reed.edu.
