R help - Dec 2010 - Nested layout()

Hello,

Is it possible to call a graphing function that uses layout() multiple times and
layout those outputs ? Here's a minimal example :

myplot <- function()
{
	layout(matrix(1:2, nrow=1), widths = c(1, 1))
	plot(1:10)
	plot(10:1)
}

layout(matrix(1:2), heights = c(1, 2))
myplot()
myplot()

layout() will always start a new layout of plots. AFAIK there's no way
to make it recursive.

Hi Dario,
Try split.screen followed up by subplot in the TeachingDemos package.

split.screen(c(2,2))
screen(1)
plot(1:10)
subplot(plot(rnorm(5)),c(1,5),c(5,10))
screen(2)
plot(1:10)
subplot(plot(rnorm(5)),c(1,5),c(5,10))
screen(3)
plot(1:10)
subplot(plot(rnorm(5)),c(1,5),c(5,10))

The final plots are left as an exercise.
