Pulling off legend (with opts(keep='legend_box')) appears to be broken in 0.9

I had the functionality described in this wiki post

https://github.com/hadley/ggplot2/wiki/Share-a-legend-between-two-ggplot2-graphs

set up and running beautifully with ggplot2 version 0.8.9. After our system underwent some maintenance, we had to reinstall all of our packages and ggplot2 0.9 was installed. As it turns out, this broke the functionality of opts(keep='legend_box'). Adding that option did not remove plot, as expected. After reinstalling 0.8.9, we got back the desired behavior.

Is there a new way of doing this, or is this a bug? If the former is the case, could the above wiki post be updated?

Thanks, and best regards

You can't use this opts() anymore, instead you need to extract the legend from gtable, which is probably work in progress (gtable package). I've updated the wiki page with a way to do it manually.

Great - thanks!

Thanks for the hard work. No way to get this backward compatible?

It's not a priority at this point, because it's not commonly used. Sorry!
