How to create a violin plot with ggplot2 in R with geom_violin and geom_dotplot (CC092)

One of the trendy data visualization methods is a violin plot. In this Code Club, Pat will show you how to create a violin plot in ggplot2 with geom_violin and how to show individual data points on the plot with ggplot2's geom_jitter and geom_dotplot functions. We'll also see how to indicate specific quantiles on the plot.

Pat will use RStudio and functions from the #ggplot2 package including #geom_violin, #geom_jitter, and #geom_dotplot and functions from other packages from the tidyverse. The accompanying blog post can be found at https://www.riffomonas.org/code_club/....
