I have 2D landmarks data (x,y) of bones and I plot it using the function plot in R language.

The problems:

Since the x-axis and y-axis have the same unit, I want the plot to have an actual size.

The length between 150 and 350 on the x-axis must be half the length between 100 and 500 in the picture.

png("picture.png") 
plot(data)   
dev.off()

This is the code that I use to save the picture on my computer.

Set `asp = 1` in your `plot` command to set the aspect ratio to 1. – Gregor Thomas Oct 10 '22 at 18:02
You may also want to use the `height` and `width` arguments of `png()` to set a an appropriate size. See the `?png` help page for examples. – Gregor Thomas Oct 10 '22 at 18:03
