You know how to make ggplot2 graphics, right? No worries. Piece of cake.

Now, can you please rotate the x axis labels to vertical?

ggeasy is here to make that a little easier.

You can install ggeasy from github with:

# install.packages("devtools")
devtools::install_github("jonocarroll/ggeasy")

library(ggplot2)
library(ggeasy)

ggplot(mtcars, aes(hp, mpg)) + 
    geom_point() + 
    easy_rotate_x_labels()
