### Visualization for Data Science Using R

Angela Zoss

**Summary**

This course is designed for two audiences: experienced visualization designers looking to apply open data science techniques to their work and data science professionals who have limited experience with visualization. Participants will develop skills in visualization design using R, a tool commonly used for data science.

**Why Take This Course?**

Data science skills are increasingly important for research and industry projects. With complex data science projects, however, come complex needs for understanding and communicating analysis processes and results. Ultimately, an analyst’s data science toolbox is incomplete without visualization skills. Incorporating effective visualizations directly into the analysis tool you are using can facilitate quick data exploration, streamline your research process, and improve the reproducibility of your research.

**What Will Participants Learn?**

The course will take a project-based approach to learning best practices for visualization for data science. Participants will be guided through several sample analysis and visualization projects that will highlight different types of visualization, different features of R and its visualization libraries, and different challenges that arise when trying to apply an open data science philosophy to visualization. In short, students will learn the following:

- introduction to visualization in R
- basic syntax for ggplot2
- applying common graphic design principles to ggplot2 visualizations
- using Shiny to create interactive websites that include R data and visualizations

**Prerequisites and Requirements**

Participants should bring laptops to this course. Basic familiarity with R is required. We will use RStudio to interact with R, and all exercises will be distributed in RMarkdown files (rather than simple R script files). This allows us to combine R code with non-code elements and promotes a literate programming approach to research.

This course assumes basic familiarity with R — e.g., R syntax, data structures, development environments. Visualizations will be created with ggplot2 and other tidyverse libraries, but prior experience with those libraries is not required. In order to fully participate in class exercises, participants should install the following on their laptops: current versions of R, RStudio, the tidyverse package, and the knitr package (optional).

### Working with Messy Data
