[R] Base and lattice graphics on the same graphics page

Although base graphics does not mix with lattice in the one graph,
I've found that print.trellis(position=..., ) and the use of 
to put regular and trellis graphics on the one graphics page works
like a treat, at least in version 2.0.1 of R.  [Base graphics functions
that are themselves inconsistent with par(fig=...) are obviously

I am wondering whether there are caveats of which I and others
should be aware, or whether there is a risk that the ongoing
development of R's graphics abilities will render such a cohabitation
unworkably fractious.


gph <- bwplot(voice.part ~ height, data=singer)
print(gph, position=c(0, 0.5, 1, 1)) # x0, y0, x1, y1
par(fig=c(0, 1, 0,0.5), new=TRUE) # x0, x1, y0, y1
boxplot(height ~ voice.part, data=singer, horiz=TRUE)
