This article will show you, step by step, how to combine multiple ggplots on the same page, as well as, over multiple pages, using helper functions available in the following R package: ggpubr R package, cowplot and gridExtra. Testthat doesn't work any more on the class of ("gg" "ggplot" "ggarrange""). It can be also a vector containing the color names for each stratum. Note that, its also possible to annotate the output of the grid.arrange() function using the helper function draw_plot_label() [in cowplot]. I have no idea of Grobs etc whatsoever, but I hacked together a solution for two plots, should be possible to extend to arbitrary number but its not in a sexy function: If the legend is the same for both plots, there is a simple solution using grid.arrange(assuming you want your legend to align with both plots either vertically or horizontally). get_legend().

Other arguments are passed on to arrangeGrob , including named arguments that are not defined for grid_arrange_shared_legend . labels, relative to each subplot. To arrange multiple ggplots on one single page, well use the function ggarrange()[in ggpubr], which is a wrapper around the function plot_grid() [in cowplot package]. Before using the arrange function, your R environment must have the dplyr library installed. Note that this will require library(grid) in addition to library(gridExtra). This article describes how to combine multiple ggplots into a figure. 0.1.4.999). to your account, I have been using ggarrange for a while and love the way it easily combines ggplot figures.
