It's not too hard to use rect() to add shading to the boxplots. The boxes
are centered on consecutive integers and the width is +/- .4. The boxplot()
function returns the quartiles of each box.
set.seed(42)
DF <- data.frame(val=rnorm(150), grp=rep(letters[1:6], 25))
outstat <- boxplot(val~grp, DF) # save the boxplot stats
ngroups <- length(levels(DF$grp)) # get number of groups
dval <- c(6, 6, 6, 12, 12, 12) # density vals for each group
aval <- c(0, 30, 60, 90, 120, 150) # angle vals for each group
rect((1:ngroups)-.4, outstat$stats[2,], (1:ngroups)+.4, outstat$stats[4,],
density=dval, angle=aval) # draw the rectangles
You can also play with lty= and lwd= but that will affect the box border as
well.
