Dear all, I would like to draw two plots in the same device so that there is a single row and two columns, with the first column being 1/3 of the device's width. I am creating a PNG object with width = 30 and height = 20 cm. I know that I should use split.screen or layout but I am lost with the matrix to pass to the functions. For istance, I tried: # distance in arbitrary units (so let's say cm) from of corners # left, right, bottom, and top counting from bottom left corner # that is first panel has the bottom right corner 20 cm from the bottom left?> m = matrix(c(0,20,40,0, 20,60,40,0), byrow=T, ncol=4) > m[,1] [,2] [,3] [,4] [1,] 0 20 40 0 [2,] 20 60 40 0> split.screen(m)Error in par(split.screens[[cur.screen]]) : invalid value specified for graphical parameter "fig"> m[1,][1] 0 20 40 0> split.screen(m[1,])Error in split.screen(m[1, ]) : 'figs' must specify at least one screen What should be the syntax for this task? -- Best regards, Luigi
?layout Please read the Help file **carefully** and work through the **examples**. I cannot explain better than they. Here is code using layout() that I think does what you want: m <- matrix(1:2, nrow =1) layout(m, widths = c(1,2)) plot(1:10, type = "p",main = "The First Plot") plot(10:1, type = "l", main ="The Second Plot") Note that both the lattice package and ggplot2 can also do this sort of thing much more flexibly(and therefore requiring more effort to learn).

And bottom first, so ... m = matrix(c(0,20,0,40, 20,60,0,40)/100, byrow=T, ncol=4) ... will work.

Incidentally, here is another way to do what (I think) you asked using layout(): m <- matrix(c(1,2,2), nrow =1) layout(m) plot(1:10, type = "p",main = "The First Plot") plot(10:1, type = "l", main ="The Second Plot") On my device, the plots use different size fonts, point sizes, etc. and so aesthetically differ. I do not know why and am too lazy to delve into the code.
