R: Data Analysis and Visualization

Setting graph margins and dimensions

In this recipe, we will learn how to adjust graph margins and dimensions.

Getting ready

All you need to try out in this recipe is to run R and type the recipe in the command prompt. You can also choose to save the recipe as a script so that you can use it again later on.

How to do it...

We can use the fin and pin arguments of the par() command to set the figure region and plot dimensions:

par(fin=c(6,6),
pin=c(4,4))

We can use the mai and omi arguments to adjust the inner and outer margins, respectively:

par(mai=c(1,1,1,1),
omi=c(0.1,0.1,0.1,0.1))

How it works...

All the mentioned arguments accept values in inches as a pair of width and height values. The default values for fin and pin are approximately 7 x 7 and 5.75 ...
