Create subplots in a subplot in R

I'm trying to arrange my plots as shown in the figure in R.

I can create a 2 by 2 plot matrix using:

par(mfrow=c(2,2)) 

Is it possible to further create subplots within the 4th square as shown in the figure?

Thanks!

You can use the layout function to arrange graphics plots. layout takes a matrix that indicates the order in which to add plots to the graphics device.

m1 <- matrix(c( 1, 1, 2, 2, 1, 1, 2, 2, 3, 3, 4, 5, 3, 3, 6, 7), nrow = 4, ncol = 4, byrow = TRUE) m1 # [,1] [,2] [,3] [,4] # [1,] 1 1 2 2 # [2,] 1 1 2 2 # [3,] 3 3 4 5 # [4,] 3 3 6 7 layout(m1) hist(rnorm(100), col = "red") hist(rnorm(100), col = "orange") hist(rnorm(100), col = "yellow") hist(rnorm(100), col = "green") hist(rnorm(100), col = "lightblue") hist(rnorm(100), col = "blue") hist(rnorm(100), col = "violet") 

You will need to make sure the graphics device is large enough to receive large numbers of plots.
