Workshop materials and instructions for the 2023-09-12 Introduction to Data Visualization in R virtual workshop, led by JHU Data Services.
This workshop introduces data visualization in R using base R and ggplot2. In this hands-on workshop, we cover design concepts of data visualization and popular R packages, before diving into creating data visualizations for a prepared dataset using base R and ggplot2.
- If you haven’t already, make sure you have downloaded and installed the following software:
- R - https://cran.r-project.org/
- RStudio - https://www.rstudio.com/products/rstudio/download/ (Download “RStudio Desktop”, not “RStudio Server”)
- If it’s been a while since you’ve used R or R Studio, no worries! But check your versions and consider updating if you’re several versions behind.
In this workshop, we’ll be using a number of R packages. Please try to install them prior to the workshop starting, as some of these packages can take a while to install. Make sure you’ve installed the following R packages:
- ggplot2 (for plotting)
- palmerpenguins (our data)
- RColorBrewer (for generating colorblind friendly color palettes)
To install the packages, use the following commands in your R console:
install.packages("ggplot2")
install.packages("palmerpenguins")
install.packages("scales")
install.packages("RColorBrewer")- presentation-materials: This folder contains PowerPoint slides and other presentation materials used in the workshop
