When creating plots in R base they will be opened in a new window. However, you may need to customize the height and width of the window, that defaults to 7 inches (17.78 cm). For that purpose, you can use of the height and width arguments of the following functions, depending on your system. It should be noted that in RStudio the graph will be displayed in the pane layout but if you use the corresponding function, the graph will open in a new window, just like in R base. In addition to being able to open and set the size of the window, this functions are used to avoid overriding the plots you create, as when creating a new plot you will lose the previous. Note that in RStudio you can navigate through all the plots you created in your session in the plots pane. While (dev.cur() > 1) dev.off() # Equivalent You can also clear the plot window in R programmatically with dev.off function, to clear the current window and with graphics.off, to clear all the plots and restore the default graphic parameters. Note that the dev.cur function counts the number of current available graphics devices.

You can use this to combine several plots in any arrangement into one graph. You have to experiment to get it just right.įig= starts a new plot, so to add to an existing plot use new=TRUE. Again, I chose a value to pull the right hand boxplot closer to the scatterplot. The right hand boxplot goes from 0.65 to 1 on the x axis and 0 to 0.8 on the y axis. I chose 0.55 rather than 0.8 so that the top figure will be pulled closer to the scatter plot. The top boxplot goes from 0 to 0.8 on the x axis and 0.55 to 1 on the y axis. The first fig= sets up the scatterplot going from 0 to 0.8 on the x axis and 0 to 0.8 on the y axis. The format of the fig= parameter is a numerical vector of the form c(x1, x2, y1, y2). To understand this graph, think of the full graph area as going from (0,0) in the lower left corner to (1,1) in the upper right corner. Mtext("Enhanced Scatterplot", side=3, outer=TRUE, line=-3) Plot(mtcars$wt, mtcars$mpg, xlab="Car Weight",īoxplot(mtcars$wt, horizontal=TRUE, axes=FALSE) In the following example, two box plots are added to scatterplot to create an enhanced graph. Creating a figure arrangement with fine control # column 2 is 1/4 the width of the column 1 # One figure in row 1 and two figures in row 2 Absolute widths (in centimetres) are specified with the lcm() function. Relative widths are specified with numeric values. Heights= a vector of values for the heights of rows. Widths= a vector of values for the widths of columns Optionally, you can include widths= and heights= options in the layout( ) function to control the size of each figure more precisely. Mat is a matrix object specifying the location of the N figures to plot. The layout( ) function has the form layout( mat ) where Plot(wt,disp, main="Scatterplot of wt vs disp")Ĭlick to view # 3 figures arranged in 3 rows and 1 column # 4 figures arranged in 2 rows and 2 columns mfcol=c( nrows, ncols ) fills in the matrix by columns. With the par( ) function, you can include the option mfrow=c( nrows, ncols ) to create a matrix of nrows x ncols plots that are filled in by row. R makes it easy to combine multiple plots into one overall graph, using either the
