Creating a jitter plot / stripchart with ggplot2's geom_jitter and stat_summary in R (CC090)

You can create a jitter plot or stripchart with R's ggplot2 package using the geom_jitter function. A jitter plot or strip chart are the same thing and they allow you to depict individual values of a continuous variable against categorical variable. To provide context, we can also use stat_summary to include a marker to indicate the median value of the continuous variable. In this episode of Code Club, Pat will show you how to create a jitter plot using geom_jitter and stat_summary from ggplot2. Pat will use RStudio and functions from the #ggplot2 package including #geom_jitter and #stat_summary and other packages from the tidyverse. The accompanying blog post can be found at https://www.riffomonas.org/code_club/2021-04-09-stripchart. Do you have a figure that you would like to receive a critique or help improving?
