It is often desirable to minimize ink in a plot. I have a faceted plot (facet_wrap) and would like to remove as much ink as possible yet maintain readability.
facet_wrap
This should simplify things considerably:
library('ggthemes') ggplot(mtcars, aes(mpg, hp)) + geom_point() + facet_wrap(~carb, scales='free') + theme_tufte() + theme(axis.line=element_line()) + scale_x_continuous(limits=c(10,35)) + scale_y_continuous(limits=c(0,400))
