plot.background doesn't work in 0.9.2

[Tengfei]

Dear all,

Looks like the example for changing plot.background in theme function doesn't work properly, here is the code

z <- ggplot(mtcars, aes(wt, mpg, colour = factor(cyl))) + geom_point()

z + theme(plot.background = element_rect(fill = "green"))

I didn't see any change in the plot.

Do I miss anything?

Thanks

Are you using the latest version from CRAN? This was a problem in the
initial 0.9.2 release candidate, but it has been fixed. That version
reported itself to be 0.9.2, even though it was just a release
candidate.

Hi Winston,

Thanks a lot! It works after I updated to the latest version of ggplot2 0.9.2 on CRAN.

cheers
