[R-sig-eco] Problem with strip names in bwplot (lattice)

[Augusto Ribas]

Hello, i'm haveing difficulties to write correctly a strip name in a
lattice plot.

Here is a data example:

resposta<-rnorm(90)
preditor1<-rep(rep(c("a","b"),each=15),3)
preditor2<-rep(c("sp1","sp2","sp3"),each=30)

library(lattice)

#species names need to be in italic, so i wrote them like this
bwplot(resposta~preditor1|preditor2,
       strip = strip.custom(factor.levels = c(
                                expression(italic("P. paradoxa")),
                                expression(italic("H. raniceps")),
                                expression(italic("P. azurea")))
                            )
       )

#but i wanted a second line, with more information, but no in italic, so in
the foruns, i saw a
#solution useing atop from expression function

bwplot(resposta~preditor1|preditor2,
       strip = strip.custom(factor.levels = c(
                                expression(atop(italic("P. paradoxa"),"side
information")),
                                expression(atop(italic("H. raniceps"),"side
information")),
                                expression(atop(italic("P. azurea"),"side
information")))
                            )
       )

But the text get out of the strip, is there a way to increase the strip
size, to fit all the text, or maybe another solution to put 2 lines of text
in each strip, keeping the species name in italic?
