Thanks for the reply.
It works fine for a single plot-call.
But as soon as I call layout() before plotting I again run into the problem
that plots are not drawn into one graphic device but another one is opened for
the second plot-call.
see here;
setHook("plot.new", function()
par(bty='n',
cex=0.8,
las=1,
ann=F,
lwd=2,
mar=c(5, 4, 2, 1),
oma=c(0,0,0,0),
pch=19,
xpd=T,
cex.axis=0.85,
mgp=c(2.5, 0.72, 0),
tcl=-0.4
)
)
layout(matrix(1:2, 1, 2, byrow=T))
plot(c(1,2,3))
plot(c(3,2,1))
