How do I specify axis thickness in a plot? (in R)

Question

I am using using plot(), matplot() and ggplot(). I am guessing the answer will be the same for all of them.

I want to specify the thickness of the y-axis, the x-axis, and the other two lines that constitute the box around the plot, all separately. How can I achieve that?

Thanks in advance.

Note: I have already read this - Increasing the thickness of box lines in an R boxplot? , but I want to change the thickness of the individual axis lines separately.

Answer 1

You mean list this?

plot(sample(100))

axis(side = 1, lwd = 2)
axis(side = 2, lwd = 2)

Answer 2

See ?axis and use it along with plot(). Here is a nice tutorial.
