ggplot2: How to rotate a graph in a specific angle?

Question

I would like to rotate a ggplot2 graph by a self-specified angle. I found how to rotate the axis text with element_text(angle = 20). I would like to do somethin

Answer 1

Here's a rough idea, calling your plot p:

library(grid)
pushViewport(viewport(name = "rotate", angle = 20, clip = "off", width = 0.7, height = 0.7))
print(p, vp = "rotate")

You'll probably want to tailor the width and height to the angle and aspect ratio you want.
