Event Details

Introduction to Data Visualization in R: ggplot in R is the fourth class in the NIH Library Introduction to R Series. A basic understanding of R and R Data Types is expected. This class provides a basic overview of producing scatter plots, boxplots, and time series plots using ggplot. R is a programming language and open source environment for statistical computing and graphics. The R class series is a comprehensive collection of training sessions offered by the NIH Library Data Services Program that is designed to teach non-programmers how to write modular code and to introduce best practices for using R for data analysis and data visualization. Each class uses both evidence-based best practices for programming and practical hands-on lessons.

By the end of this class students should be able to: understand the basics of plotting in ggplot; demonstrate how to add a layer to a plot using ggplot; define ggplot aesthetics; add a geometric function to a plot; produce boxplots, and time series plots using ggplot; set universal plot settings; describe what faceting is and apply faceting in ggplot; modify the aesthetics of an existing ggplot plot (including axis labels and color); build complex and customized plots from data in a data frame; exporting a plot using ggplot.

Students are encouraged to install R(link is external) and RStudio(link is external) and download the class data before the class so that they can follow along with the instructor. Attendees will need to download the class data before the class.
