Hi: I would think that, at least in principle, this should work:
a <- ggplot(mtcars, aes(qsec, wt)) a + geom_point() + stat_smooth(fill="blue", colour="darkblue", size=2, level = 0.9, alpha = 0.2) + stat_smooth(fill = 'blue', colour = 'darkblue', size = 2, level = 0.5, alpha = 0.4) but geom_smooth() doesn't seem to react to different values of level. I get the same bands on geom_smooth() if I use level = 0.95, 0.75 or 0.5. Since I make it a policy not to invoke the B word, I'll let others who know more about the code comment on it. BTW, ggplot2 related questions tend to get faster responses on its list: ggpl...@googlegroups.com. I've taken the liberty of forwarding there since most of the developers read that list more regularly than R-help.
