Question

I know I can use par(mfrow=c(1, 2)) to create a plot with a split screen. However, I’d really like to create a plot where 2/3 of the window is used to plot one graph, and 1/3 of the window is used to plot another. Is this possible?

Answer 1

You need to use function layout instead of par here, with argument widths:

layout(matrix(c(1,2),nrow=1), widths=c(2,1))

See ?layout for more informations.
