set.panel.RdDivides up the graphics window into a matrix of plots.
set.panel(m=1, n=1, relax=FALSE)After set.panel is called, the graphics screen is reset to put plots according to a m x n table. Plotting starts in the upper left hand corner and proceeds row by row. After m x n plots have been drawn, the next plot will erase the window and start in the 1,1 position again. This function is just a repackaging for specifying the mfrow argument to par. Setting up a panel of plots is a quick way to change the aspect ratio of the graph (ratio of height to width) or the size. For example, plotting 2 plots to a page produces a useful size graph for including in a report. You can print out the graphs at any stage without having to fill up the entire window with plots. This function, except for the "relax" option is equivalent to the S sequence: par( mfrow=c(m,n)).
The function will echo your choice of m and n to the terminal.
