Rotate x axis tick labels — x90 • spHelper

Convenience functions to rotate x axis tick labels in ggplot plots:
x30() rotates in 30 degrees.
x90() rotates in 90 degrees.

x90()

x30()

Details

These functions correct ggplot2 theme elements and may not respond if new theme is applied after e.g. x30() is apllied. I.e. INCORRECT:
qplot(mpg, wt, data = mtcars) + x30() + theme_bw().
CORRECT:

qplot(mpg, wt, data = mtcars) + theme_bw() + x30().

Examples

library(ggplot2)
library(spHelper)

qplot(mpg, wt, data = mtcars) + x30()

qplot(mpg, wt, data = mtcars) + x90()
