R - histogram rectangles line thickness

Question

How can I get the actual lines (that form the many rectangles) on a histogram to be thicker? I would like to avoid using ggplot.

Here is some code that generates a histogram so that we have a reproducible example:

h = hist(rnorm(100),plot=F)
plot(h,lwd=4) #note, lwd does not work :(

Answer 1

You can set the line width with par():

opar <- par(lwd=2)
plot(h)
par(opar)
