Improving the appearance of a stacked barchart with ggplot2, dplyr, and forcats (CC103)

Sometimes we don't have a choice in the type of data visualization format we use. Although a stacked barchart is not ideal, there are methods for improving the appearance of stacked barcharts. In this episode of Code Club, Pat uses ggplot2, dplyr, and forcats to show how to pool rare taxa and order the more abundant taxa to give a common anchor point on the y-axis to make comparisons.


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

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!
