Hi:
Your example doesn't make much sense as stated, but is this what you had in
mind?
d <- ggplot (mtcars, aes(qsec, wt)
d + geom_point() + stat_smooth(aes(colour = factor(cyl)),
fill="darkgrey", size=2, alpha = 0.2) +
scale_colour_discrete("No. cylinders")
In this case, the multiple plots were obtained by grouping on different
numbers of cylinders, which was coerced to a factor in order to use it as a
grouping variable. There are many ways to apply this 'grouping' trick in
ggplot2 using the companion plyr package, several of which can be found in
the ggplot2 list archives http://had.co.nz/ggplot2/ (look for Mailing List)
and in Hadley's book:

HTH,
Dennis
