Without your code, it is hard to know exactly what you need to resolve
the problem or why your manipulation of the margins did not work as you
want, but I am guessing that the following might be helpful.

Here is a default PDF plot:

 pdf("PDF1.pdf", height = 4, width = 4)
 barplot(1:5)
 dev.off()

 
Here is the same plot, but with the margins reduced:

 pdf("PDF2.pdf", height = 4, width = 4)
 par(mar = c(1, 3, 1, 1))
 barplot(1:5)
 dev.off()


Here is a default 2 x 2 plot:

 pdf("PDF3.pdf", height = 4, width = 4)
 par(mfrow = c(2, 2))
 barplot(1:5)
 barplot(1:5)
 barplot(1:5)
 barplot(1:5)
 dev.off()


Here is the same with reduced margins:

 pdf("PDF4.pdf", height = 4, width = 4)
 par(mfrow = c(2, 2))
 par(mar = c(1, 3, 1, 1))
 barplot(1:5)
 barplot(1:5)
 barplot(1:5)
 barplot(1:5)
 dev.off()
