Hi Yichun,
Your question is not entirely clear, but I'll try to make some 
suggestions. If what you mean is the "figure" region (that's the plot 
and the margins around it), you want something like this:

x11(width=3.15,height=7.09)
layout(matrix(c(1,3,2),ncol=1),heights=c(1,0.25,1))
plot(1:5)
plot(1:5)

If you just want plots with nothing around them, maybe this:

x11(width=3.15,height=7.09)
layout(matrix(c(1,3,2),ncol=1),heights=c(1,0.25,1))
par(mar=c(0,0,0,0))
plot(1:5,axes=FALSE)
box()
plot(1:5,axes=FALSE)
box()
