Okay, so what you really want to do is be able to set a wide right margin and draw some segments there? Using layout() is not the best way to go about this: as you've discovered, you can't control the area assigned.
You can "cheat" with layout(), as in: layout(matrix(c(1,1,1,2), nrow=1)) but the better way is to see xpd within ?par as described here: https://stat.ethz.ch/pipermail/r-help/2009-July/206311.html along with par()$mai to set the margins appropriately.
