In this tutorial, we will see examples of making barplots and coloring the barplots in a few simple ways. We will see how to color barplots manually by specifying a color of interest and how to color a barplot by another variable in the dataset. Let us load tidyverse suite of … [Read more...] about Coloring Barplots with ggplot2 in R
