From the xYplot() help page (as you can see from the comment, the
problem had been noted---although "works differently" seems to be a
euphemism for "doesn't work"--- reported by me, among others, a while
ago):
dfr <- expand.grid(month=1:12, year=c(1997,1998), reps=1:100)
month <- dfr$month; year <- dfr$year
y <- abs(month-6.5) + 2*runif(length(month)) + year-1997
s <- summarize(y, llist(month,year), smedian.hilow, conf.int=.5)
# filled bands: default fill = pastel colors matching solid colors
# in superpose.line (this works differently in R)
xYplot ( Cbind ( y, Lower, Upper ) ~ month, groups=year,
method="filled bands" , data=s, type="l")
# this produces a bright red band at the top and a black band at the
bottom
I'll be happy to submit a bug report if this doesn't count and if you
tell me how.
