Re: [R] Visualize quartiles of plot line Hi, concerning the missing se coloring: I followed the examples on http://had.co.nz/ggplot2/stat_smooth.html  c <- ggplot(mtcars, aes(y=wt, x=qsec))  c + stat_smooth()  c + stat_smooth() + geom_point()  c + stat_smooth(se = TRUE) + geom_point()  c + stat_smooth(fill=alpha("blue", 0.2), colour="darkblue", size=2)  c + geom_point() + stat_smooth(fill=alpha("blue", 0.2), colour="darkblue", size=2) Does not work, se is missing.  c + stat_smooth(fill="blue", colour="darkblue", size=2) Does work.  c + stat_smooth(method = lm, formula= y ~ ns(x,3)) + geom_point()  c + stat_smooth(method = rlm, formula= y ~ ns(x,3)) + geom_point() Does not work: "Error in model.frame(formula = formula, data = data, weights = weight,  :                  ..2 used in a wrong context, no ... to read" All other examples on the page do not work. This seems to be a bug,m right? Tell me if I can be of any use fixing this.
