Hi Vera, You need to do it in two steps, I think because the different parameters you're trying to set interact.
par(mfrow=c(3,4),mai=c(0.04,0.04,0.04,0.04), omi=c(0.2,0.32,0.32,2.16)) par(pin=c(1,0.87)) for(i in 1:12) plot(1:10, 1:10) For this level of control, you probably also want to explicitly set the dimensions of your device; see the help for whatever one you're using for more information.
