[R] space between plots

[Agustin Lobo]

I've set

layout(matrix(c(1,3,2,4),ncol=2))
and

par(mar=c(0, 4, 4, 0) + 0.0) and
par(mar=c(0, 0, 4, 3) + 0.0)

for the upper-left and upper-right plots, but
still get an space between both plots,

is there any way to completely eliminate that space?

Thanks

Agus
