For boxplots with no outlier, we will use the dataset, ldeaths, which is a dataset built into R. Note that ldeaths is a vector. The order in which to display the side-by-side boxplots. But generally, we pass in two vectors and a scatter plot of these points are plotted. However, you should keep in mind that data distribution is hidden behind each box. plot title. 1”.
