[R] grey colored lines and overwriting labels i qqplot2

[Hadley Wickham]

> You should only have one scale_ call for each scale type.  Here, you have
> three scale_colour_ calls, the first selecting a grey scale, the second
> defining a single break with its label (and thus implicitly subsetting on
> that single break value), and a second which defines a different
> break/label/subset.  Only the last one has any effect.

Just to clarify: breaks/labels control the appearance of the
legend/axis, limits modify what data is shown on the plot.
