If you find yourself always adding the same theme to your plot (i.e., we really like the
+ theme_bw()), you can use
theme_set() so your chosen theme is applied to every plot you draw:
In fact, we usually have these two lines at the top of every script:
Furthermore, we can customise anything that appears in a
ggplot() from axis fonts to the exact grid lines, and much more.
That’s what Chapter 5: Fine tuning plots is all about, but here we are focussing on the basic functionality and how different geoms work.
But from now on,
+ theme_bw() is automatically applied on everything we make.
