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 something similar with the whole plot.

Reproducible example:

set.seed(123)

data_plot <- data.frame(x = sort(rnorm(1000)),
                        y = sort(rnorm(1000)))

ggplot(data_plot, aes(y, x)) +
    geom_line() # + theme(axis.title.x = element_text(angle = 20))

This graph should be rotated:

[This answer](https://stackoverflow.com/a/24312791/903061) does it, except for the clipping, I'm sure there's a way to nest a viewport inside a bigger one to get your result. — Gregor Thomas, Jan 18 '18 at 14:50

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.
