ggplot, getting two scales and one stat.
Hi Tylere, This is a bug present in R 2.7.2 which will be fixed in the next version (which I'm trying to release ASAP) Hadley

Thanks Hadley, unfortunately doing this gives me an error:
ggplot(polls, aes(x =Date, y = Popular_Support, colour=Party)) +
+ stat_smooth(span=0.5) + + geom_point(aes(shape=Source)) Error in `[.data.frame`(df, , var) : undefined columns selected if I move it back up into ggplot, then it works fine.... ?? 2008/9/27 hadley wickham <h.wickham at gmail.com>

I have a simple plot: ggplot(polls, aes(x =Date, y = Popular_Support, colour=Party, shape=Source)) + stat_smooth(span=0.5) + geom_point() How can I get the smooth to only render along one of the scales? ie, I want to see regressions for each colour, but not each shape.
Just map shape to source only for the points: ggplot(polls, aes(x =Date, y = Popular_Support, colour=Party)) + stat_smooth(span=0.5) + geom_point(aes(shape=Source)) Hadley -- http://had.co.nz/
