Method 1: Change Legend Title Using labs() The following code shows how to create a grouped boxplot for a given dataset:Produce more meaningful labels, add a legend, and remove profit group strips. stars. However, while R offers a simple way to create such matrixes through the cor function, it does not offer a plotting method for the matrixes created by that function. This opens a whole universe of opportunities for developers: any translation product you can imagine can now be built. Now iterate over the subplots in the plot matrix and remove the legends for each of them and just retain one of them since the densities are all plotted on the same column. We will first use labs () in ggplot to specify the titles for the legend. This basically requires reading the help page and working through the examples. packages("ggplot2") # Install ggplot2 package library ("ggplot2") # Load ggplot2. Change the appearance of the main title, subtitle, caption, axis labels and text, as well as the legend title and texts. Which gives. Some of these functions include a pairwise plot matrix, a two group pairwise plot matrix, a parallel coordinates plot, a survival. graph2 <- graph1 +theme (strip.
