You mean:
split.screen(c(2, 5))

error message) or enlarging the space for the figures in another way
(larger device region etc.)?
In order to reduce the margins, e.g. use
...
screen(i)
par(mar=c(2,2,1,1))
...

I think you don't need such a complex thing like split.screen().
Another way is to use
par(mfrow=c(5, 2))
or see ?layout for a third way.
