R help - Sep 2010 - graph margins

Hello All,

I am drawing a graph having 18 small graphs inside using par(mfrow = c(6,3))
command. My problem is how to specify the margins of the whole 18 graphs. I
used par(mar=c(6.5, 6.5, 1.5, 1.5)) for each graph separately already but it
does not left any margins for the 'mtext()' for the margins of the whole
18
graphs. Any comments please.

Thanks,
MJK

Use par(oma=c(1,1,1,1))  # oma = "outer margin area"

Is this what your looking for?
