How to change the histogram borderline thickness in ggplot geom_histogram()

I have the following code:

library(ggplot2)
data(mtcars)
ggplot(mtcars, aes(x=mpg)) + geom_histogram(bins=15, colour='red')

Which produce this:

enter image description here

As stated there, how can I change the thickness of the enclosing line of the histogram?

Just tested on ggplot2, the size aesthetic for lines was deprecated in ggplot2 version 3.4.0.

You can do the same using linewidth.

ggplot(mtcars, aes(x=mpg)) + 
    geom_histogram(bins=15, colour='red', linewidth=0.2)

In addition, to program in point space, I used the following function:

MyPoints <- function(desired_points){
  return (unit(desired_points*.5*(1/1.07), "point"))
}

geom_histogram(size=MyPoints(1))

Just use size argument 

geom_histogram(bins=15, colour='red',size=2)

Easy enough :)

ggplot(mtcars, aes(x=mpg)) + geom_histogram(bins=15, colour='red',size=3)
