[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 par(fig=...)
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 disallowed.]

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.

Example:

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)
