[R] Stacked barplot with two stacked bars besides each other

[Daniel Brewer]

Thanks.
That is definitely in the right direction, but firstly I would like
yoda1:var1 next to yoda1:var2, not as currently yoda1:var1, yoda2:var1,
yoda1:var2, yoda2:var2.  Additionally, I would like the gap between
samples to be greater than the gap between variables.

Many thanks

Dan
