Examples

library(ggplot2)
library(patchwork)
p <- ggplot(mtcars, aes(x=wt, y=mpg))
p1 <- p + geom_point(position=position_identityx()) + ylim(0, 50)
# whole point layer was shifted vertically (distance=5).
# the label of axis y should be subtracted 5 to get the true value..
p2 <- p + geom_point(position=position_identityx(vexpand=5)) + ylim(0, 50)
# whole point layer was shifted horizontally (distance=5).
# the label of axis x should be subtracted 5 to get the true value.
p3 <- ggplot(mtcars, aes(y=wt, x=mpg)) +
      geom_point(position=position_identityx(hexpand=5)) + xlim(0, 50)
p4 <- p1 + p2 + p3
