You really put a lot of typing work into your example code, but it work, so
it's fine. As a first attempt, put the following before the second plot(). 

par(las=1,cex=0.5)

And think about the paper size. I suggest to have a look at lattice graphics
for this type of work as a more elegant alternative. And Hadley Wickham can
certainly tell you how to do this in ggplot47
