In many situations the way to do this is to create the initial plot and then add additional. Heights of the two rows widths c(2, 1)) Widths of the two columns Plot 1. One common task is to plot multiple data sets on the same plot. David holds a doctorate in applied statistics. R makes it easy to arrange multiple plots in the same plotting space. His company, Sigma Statistics and Research Limited, provides both on-line instruction and face-to-face workshops on R, and coding services in R. To see more of the R is Not So Hard! tutorial series, visit our R Resource page.Ībout the Author: David Lillis has taught R to many researchers and statisticians. We use the plot() command six times in succession, each time graphing one of the Y vectors against the X vector. Now we plot six graphs on the same plotting environment. The two other methods for saving plots be covered only briefly. Now we set up a plotting environment of two rows and three columns (in order to hold six graphs), using par(mfrow()) ggsave() has additional options to customize the saved plot, and these are discussed below. R programming has a lot of graphical parameters which control the way our graphs are displayed. R par () function We can put multiple graphs in a single plot by setting some graphical parameters with the help of par () function. This syntax sets up a plotting environment of A rows and B columns.įirst we create four vectors, all of the same length. R Multiple Plots Sometimes we need to put two or more graphs in a single plot. where A refers to the number of rows and B to the number of columns (and where each cell will hold a single graph). I have already setup each of the graphs separately, using similar code as the bargraph tutorials, just changing the x-axis (for the most part). Today we see how to set up multiple graphs on the same page.
