The ancient convention of "80 character lines" and R lexical rules would make this easier to read: 
```
p + geom_point(aes(size=CS3)) +
	ggtitle("Three and D Rate - All League") + 
	
	theme(axis.text = element_text(colour = "black")) +
	xlab('Defensive xRAPM') + ylab('Three Point Rate') +
	opts(panel.background = theme_rect(fill='white', colour='black')) +
	labs(size = "Catch and Shoot 3PT%") + 
	scale_size(label = percent)
```

It's a minor point, but making consistent indents would be the first thing I do if I were trying to debug someone else's stuff.
