Not much is different when we’re doing bootstrap testing; the main difference is that the replicates used to generate test ...

Labeling Euler diagram overlaps The purpose of my R package eulerr is to fit and visualize Euler diagrams. Besides the various intricacies involved in fitting the diagrams, there are many interesting problems involved in their visualization. One of these is the labeling of the overlaps. Naturally, simply positioning the labels ...
