Many functions can be used to draw multiple plots in one figure in R. Some of them are: `par()` from base R `grid.arrange()` from gridExtra package `plot_grid()` from cowplot package `ggarrange()` from ggpubr package These functions allow you to arrange multiple plots (or other graphical objects) in a grid layout with a specified number of rows or columns. You can also customize the appearance and behavior of the grid by using various arguments in each function.
