Number of subplot columns. ggsave (filename) and the complex syntax behind this R ggsave is: ggsave (filename, plot = last_plot (), device = NULL, path = NULL, scale = 1, width = NA, height = NA, dpi = 300, limitsize = TRUE, .., units = c ("in", "cm", "mm")) You will see a long list of parameters and to know what each does you can check the help section ?par. After specifying the arguments nrow and ncol,ggarrange()` computes automatically the number of pages required to hold the list of the plots.
