This course will focus on establishing a solid fundamental understanding of data manipulation and analysis with R. No prior programming experience is necessary, and students from all backgrounds are welcome. We will start with an introduction to the R command line, followed by a detailed description of R data structures and how to manipulate them. The course will continue by covering commonly used R functions and students will then learn how to write their own functions and scripts. We will also cover visualization in R using base R graphics and the ggplot2 package and common statistical analyses. For the final project, students will write an R script and functions to analyse their own data.

Students should come on the first day with the latest versions of R and RStudio loaded on their laptops. They can be obtained at:

R: https://www.r-project.org
RStudio: https://www.rstudio.com

Students who have officially enrolled in the class will be required to submit a script utilizing a function that they have written. The function should serve some useful purpose for your work by doing some sort of data manipulation, analysis, or visualization using techniques learned in the class. Try to keep the function less than 100 lines long and comment it well. The function should be accompanied by another script that gives an example of its execution. If running the function requires a special data set, send it either as a .csv file or as an R object. If you can't get the function to work, please send what you have at that point along with comments of what is working and what is not working. You will get full credit for the attempt and documentation.

All files that are part of the project should be sent to me compressed in a .zip file named, "Lastname_F_SIO296.zip", where "F" is the first initial (e.g., "Archer_E_SIO296.zip") by the end of the day on Friday, March 22. The function should be in its own .r script file. The script that executes an example of it should be in another script file. Please be sure that the zip file is self-contained, meaning that it contains all necessary data files in its own folder and I will be able to execute it. It should also not manipulate files or folders in folders other than its own. Finally, please limit the number of external packages it requires and load them at the beginning so I can make sure I have everything necessary installed on my machine.
