Question

Greetings, I am trying to create a bar chart of the data posted below (referred to in my code as topTwoTable), disaggregated by group type. I’ve scanned through multiple online forums, as well as Hadley’s website, and stuck when it comes to manually altering the fill color of the bars on the basis of treatment type.

Any thoughts?

Cheers,
Aaron

You’ll want to specify your colors with “scale_colour_manual”

I believe adding the following to the end of your current code should work.

+ scale_colour_manual(values = c("light blue"," dark blue"))
