main title x title and y title with ggplot2
I had the same problem and found a solution in some forums. Try this:
p<-ggplot(data, aes(x,y,fill)) + geom_point() + scale_x_continuous("your
xlabel") + scale_y_continuous("your ylabel")
The new (more ggplot-like way) is to do: ggplot(data, aes(x,y,fill)) + ... + opts(title = "my title") Hadley -- http://had.co.nz/
