In this post, we will show how to move the strip label to the… Continue reading How to Move Facet strip label to the bottom
4 Ways to have Plots Side by side in ggplot2
In this post, we will learn how to combine two plots side-by-side using four different approaches. First, we will show how we can use facet_wrap() function in ggplot2, if we are interested in similar plots (small multiples) side by side. Next three approaches are more general, i.e. combining any two plots side by side using… Continue reading 4 Ways to have Plots Side by side in ggplot2
