What does that have to do with the answer you got ? did you even try it ?
here it is (again) but this time mixing base+grid:

require(gridBase)
pdf("test.pdf")
grid.rect(gp = gpar(fill="blue"))
grid.newpage()
grid.rect(gp=gpar(fill='blue'))
# mix in base+grid. adapted from ?gridPAR in gridBase
par(fig=gridFIG(), new=TRUE)
 plot(1:10)
# plot.new()  # uncomment to see it's unnecessary
plot(1:10)
 pushViewport(viewport(width=0.5, height=0.5)) ;
grid.rect(gp=gpar(col="grey", lwd=2))
plot(rnorm(10))
grid.newpage()
grid.rect(gp=gpar(fill='blue'))
dev.off()

Then you may have noticed the dendrogram examples in the gridBase docs
don't use plot.new() either but use lattice for the layout.


In order to do that I have to call plot.new() at some point in my code
