[R] Bar Plot ggplot2 Filling bars with cross hatching

[stephen sefick]

what is your suggestion for distinguishing between many bars without
color?  I have grown up in the time of standarized tests - good or bad
I never felt nauseous.

Tufte's book (The Visual Display of Quantitative Information) has a section on why cross-hatching should be avoided (unless of course your goal is to induce nausea in the observer rather than convey information).

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
