Change the size of a plot when plotting multiple plots in R

Question

I want to know if there is a way to define the size of a plot in R, when you are plotting different plots using the par(mfrow=c()) function.

As a simple example take thi

Answer 1

Try layout for example

layout(matrix(c(1,1,2,3,4,4), nrow = 3, ncol = 2, byrow = TRUE))
plot(1,main=1)
plot(2,main=2)
plot(3,main=3)
plot(4,main=4)

layout(matrix(c(1,1,2,1,1,2,3,4,4), nrow = 3, ncol = 3, byrow = TRUE))
plot(1,main=1)
plot(2,main=2)
plot(3,main=3)
plot(4,main=4)

give you

Also you can use par(fig= ) for example

par(mar=c(2,2,2,1))
par(fig=c(0,7,6,10)/10)
plot(1,main=1)
par(fig=c(7,10,6,10)/10)
par(new=T)
plot(2,main=2)
par(fig=c(0,7,0,6)/10)
par(new=T)
plot(3,main=3)
par(fig=c(7,10,0,6)/10)
par(new=T)
plot(4,main=4)

Give you

but i think layout better for use

Answer 2

another option would be to use ggarrange. the nice thing about it is that you can use ggarange not just on plots but also on "arranged" plots that you've created with ggarrange, which makes it easy to first arrange e.g. two smaller plots and then arrange them together with one bigger one.
