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 <[EMAIL PROTECTED]> > On Sat, Sep 27, 2008 at 1:08 AM, Tylere Couture <[EMAIL PROTECTED]> > wrote: > > 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/ > [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
