Thank you! This sounds good and easy to do (if I can as well make
stripes to the legend)

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.

Thank you. I saw these postings, but I don't want to learn lattice

for

this reason (was afraid to have to change then everything else in my
graph). Anyway, I now tried with different shades of greyscale (4
shades). I'm not fully satisfied with it, but it's ok. It's for a
publication and depending on whether I have to change the graph, I
decide to either put texture in some boxes manually or still look

for a

solution in R.

Probably not. See http://r.789695.n4.nabble.com/Boxplot-Fill-

What exactly are you doing?  There may be a workaround or

alternative.
