Thank you, Uwe,
I probably phrased my question wrong, but I'm not into compiling my own
software.
Thank you Martin,
It was definitely worth the few weeks spent learning to use the grid
package.
I want to share with others making that same step some of the functions I
wrote as I tried to convert from the graphics mindset to the grid.graphics
mindset.
gtext<-function(x=0.5,y=0.5,label="gtext()",adj=0.5){
if(adj==1) {
grid.text(x=x,y=y,default.units="native", label, just="right")
} else {
if(adj==0) {grid.text(x=x,y=y,default.units="native", label,just="left")
} else {
grid.text(x=x,y=y,default.units="native", label,just="center")
}}}
glines<-function(x,y) grid.lines(x,y,default.units="native")
gpol<-function(x,y,fill=grey(0.5)) grid.polygon(c(x,x[1]),c(y,y[length(y)]),
gp=gpar(fill=fill),default.units="native")
garrows<-function(){
grid.arrows(x=c(0,105),y=0,length=unit(2,"mm"),angle=10,default.units="nati
ve")
grid.arrows(x=0,y=c(0,105),length=unit(2,"mm"),angle=10,default.units="nati
ve")
}
grect<-function(x,y,x2,y2) {
grid.rect(x,y,x2-x,y2-y,
default.units="native", just=c("left","bottom"))
}
gbalk<-function(lijn=1,x1=0,x2=1,label=label){
vp<-viewport(x = x1, y = lijn-1, w = x2-x1, h = 1,
default.units="native", just = c("left", "bottom"))
pushViewport(vp)
grid.rect()
grid.text(label) #(,x=0,just="right")
popViewport()
}
To see how I used these, look at

Unless Jeroen is really keen on learning how build R from source
on MS Windows, I think Jeroen's time might be better invested in
learning to use the "grid" package instead of "graphics".
I think layout() in "graphics" is really just a poor man's
version of using layout.grid() and viewports as provided by the
"grid" package {and as used extensively by the "lattice" package}.
