[BioC] Plot function

[Joyce Gu]

Hello,
I follow the documentation to execute the following common line to see swirl 
example,
> maDiagnPlots1(swirl[,3],title="Swirl array 93: Diagnostic 
Plots",save=TRUE,fname="t.jpg",dev="jpeg")

it give the the following error message. 
Error in plot.new() : Figure margins too large

How do I change the figure margins? This is example come with marrayClasses 
packages.

Any help is great appreciated.
Thanks
