A grouped bar chart plot can be an effective way to represent the variation across a continuous variable for multiple levels of two categorical variables. These plots can be made in R using the geom_col and position_dodge functions from the ggplot2 R package. Watch this episode where Pat will demonstrate how to create barplots. Although these are superior to stacked barcharts, there are still problems with barcharts that he will discuss in this episode of Code Club.
Pat will use RStudio and the #geom_col and #position_dodge functions from the #ggplot2 package. The accompanying blog post can be found at https://www.riffomonas.org/code_club/....
