Find the Size of the Plotting Window in R

The plotting window size can be found by using dev.size function and we can pass in for inches and cm for centimeters. For example, if we create a plot then we can use dev.size("in") to find the plot size in inches and dev.size("cm") to find the size in centimeters.

Example

Consider the below vectors and create a point chart between those vectors −

 Live Demo

x<-rnorm(10)
y<-rnorm(10,500,35)
plot(x,y)

Output

Now finding the plotting window size −

Example

dev.size("in") # in inches

Output

[1] 5.760417 5.750000

Example

dev.size("cm") # in centimeters

Output

[1] 14.63146 14.60500

This will change if we drag the plotting window to right, left, upper or down side as shown below (dragging the plotting window to left) −

Now again finding the size −

Example

dev.size("in")

Output

[1] 6.614583 5.750000

Example

dev.size("cm")

Output

[1] 16.80104 14.60500

This will not change until and unless we do not increase the plotting window manually.
