Unfortunately it's a bug in ggplot2 which I really really hope to fix this summer.
You can always place the legend manually - but since the label is still stacked/vertical, it kind of looks ugly. I really hope hadley finds time to fix this :-) p Margin = unit(c(6,0,0,0), "lines")).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
