Re: [R] help to polish plot in ggplot2
baptiste, I have two more questions. How can I get the category labels right justified? It seems that I need to change the size of the text too. Since in my real data the text size are big and they appears to be even bigger than my plot area. So, my second question is how can I change the text size? Thanks again for your help.
