Facetting is a great way to show relationship between more than two variables. When you have three variables, with faceting one can splot a single plot into smaller plots with subset of data corresponding to the third variable. In ggplot2, we can easily make facetted plot using facet_wrap() function. When you use facet_wrap() in ggplot2,… Continue reading How To Change facet_wrap() Box Color in ggplot2?

How To Make Grouped Violinplot with ggplot2 in R?
In this tutorial, we will see examples of how to make grouped violinplots using ggplot2’s geom_violin() function. Violinplots are like boxplot for visualizing numerical distributions for multiple groups. In comparison to boxplot, Violin plot adds information about density of distributions to the plot. A grouped violin plot is great for visualizing multiple grouping variables. Let… Continue reading How To Make Grouped Violinplot with ggplot2 in R?
