Applying theme moves ylab

[Brandon Farr]

I've noticed that applying a theme can play tricks with the position
of the y-axis label. When the following is run, the y-axis label is
centered on the y-axis initially:

qplot(mpg, wt, data = mtcars)

Then when the following is run, the y-axis label moves down,
practically off the plot:

last_plot() + theme_bw()

Any thoughts,
Brandon

You can add

+ opts(axis.title.y = theme_text(size = 12, vjust = 1/2, angle = 90))

or a variant to the end of the plot, that should fix it. Hadley has
fixed it for the next release I believe.

Cheers

Thanks, that works. I'm glad to hear it's been fixed for the next
release.

All the best,
Brandon
