R help - Mar 2011 - ggplot, transformation, and ylim

Hey everyone,

I'm having a little trouble with ggplot. I have two sets of y-values, one
whose range is contained in the other. Due to the nature of the y-values, I
wish to scale the y axis with a log base two transformation. Furthermore, I
wish to plot the two sets of y-values as boxplots in separate graphs with
the same ylim (and thus with the same ticks and tick labels). As of now, I
have:
ggplot(data, aes(x1, y1))+geom_boxplot()+scale_y_log2()
ggplot(data, aes(x2, y2))+geom_boxplot()+scale_y_log2()
which successfully creates the boxplot and transforms the y-axis. However, I
can't figure out how to change the range of the y-axis so that they're
the
same in both graphs. Inserting "+scale_y_continuous(limits=c(...))"
before
or after "+scale_y_log2()" doesn't seem to work. I also tried:
qplot(x1,y1,geom="boxplot", ylim=c(...))+scale_y_log2()
but my efforts were in vain. Any ideas?

Thanks.

Cheers,
Godwin

Hey everyone,

Nevermind, I figured it out:
ggplot(data, aes(x1, y1))+geom_boxplot()+scale_y_log2(lim=c(...))
:)
