In this tutorial, we will learn how to order facet variable in a grouped boxplot by mean difference between groups in each facet plot with ggplot2. We will use Palmer penguin dataset to make a grouped boxplot using facet_wrap() in ggplot2. Our data looks like … [Read more...] about How to order facet variable in grouped boxplot by mean difference between groups in ggplot2

How to Deal with Outliers in boxplot with ggplot2
In this post, we will learn of two ways to deal with outlier data points while making a boxplot. By default, ggplot2 boxplot() identifies the outliers and disply them as black dots at the boxplot extremes. One of the options to deal with outlier is to ignore them. With ggplot2, … [Read more...] about How to Deal with Outliers in boxplot with ggplot2
How to Move Facet strip label to the bottom
In this tutorial, we will learn how to move the strip label title text in ggplot2's facet* functions to the bottom. By default, facet_wrap() creates a box for each strip with a label at the top of the small multiple plot. In this post, we will show how to move the strip label to … [Read more...] about 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, … [Read more...] about 4 Ways to have Plots Side by side in ggplot2
How to add text annotation to heatmap with ggplot2
In this post, we will see how can we add text annotation to heatmaps made with ggplot2. In ggplot2, we can make simple heatmaps using ggplot2's geom_raster() and geom_tile(). In this post, we will use geom_text() to add text annotation, i.e. numerical values in the heatmap. We … [Read more...] about How to add text annotation to heatmap with ggplot2
