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)) On 20 Jul 2015, at 17:48 , Duncan Murdoch <murdoch.dun...@gmail.com> wrote: > On 20/07/2015 11:27 AM, Martin Batholdy via R-help wrote: >> Hi, >> >> I am looking for a way to modify the basic setup for any kind of plot. >> (everything that is set with the par function – like margins, cex, las etc.) >> >> I want to do this once – preferably across R sessions and not individually >> before every plot. >> >> >> My first attempt was to add a par() with all my own defaults to the >> .Rprofile file. >> This obviously does not work because par opens a new drawing device, >> applying its effect only to this device. >> >> My next attempt was to write my own version of all basic plot functions >> (like plot, barplot etc.) adding a par() call within these functions. >> This works but only if I draw a single plot.
