How to get two windows with different plots

Question

When we have a window with plots, is there a way to tell R to display a new plot in a new window?

Answer 1

You might actually want to partition the window instead so you can have mutuple plots in the same window if you are comparing them:

The following will create 3 horizontal partitions:

par(mfrow = c(3,1))

So with 3 plots it will look like the following in a single Window:

Answer 2

plot(1:1)
dev.new()
plot(2,2)
dev.set(dev.prev()) # go back to first
title(main="test dev 1")

dev.set(dev.next()) # go to second
title(main="test dev 2")

Answer 3

Create a new one:

plot(1:10)
x11()            # This has aliases on different OSes
plot(10:1)
