Have you ever wondered how to add lines with asterisks to denote statistical significance on a plot you've made with ggplot2? In this episode of Code Club, Pat will walk you through performing a series of statistical tests with kruskal.test and pairwise.wilcox.test and how to use geom_line and geom_text to draw the lines and stars.
Pat will use RStudio and base functions including #kruskal.test and #pairwise.wilcox.text and the #geom_line and #geom_text functions from the #ggplot2 package and other packages from the tidyverse. The accompanying blog post can be found at riffomonas.org/code_club/2021...
Do you have a figure that you would like to receive a critique or help improving? Let me know and I'd be happy to arrange a guest appearance!
