?split.screen
?layout

are alternatives to par(mfrow = c()), but I think you need to look at 
the margins of the plots and reduce them to suit your purposes. See ?par 
and argument mar. For example:

oldpar <- par(mfrow = c(2,2), mar = c(3,3,1,1) + 0.1)
plot(1:10)
plot(1:10)
plot(1:10)
plot(1:10)
par(oldpar)

# or

layout(matrix(c(1,2,3,4), 2, 2, byrow = TRUE))
layout.show(4)
oldpar <- par(mar=c(3,3,1,1) + 0.1)
plot(1:10)
plot(1:10)
plot(1:10)
plot(1:10)
par(oldpar)

There is no room for labels/titles but adjust the mar to suit your 
requirements.
