[BioC] Title for a matplot

[Dennis.Burian at faa.gov]

Dear all,

I ran the following command to add a title to a matplot the logic being
that the help for matplot refers the reader to the help for plot.  As you
can see, matplot doesn't recognize the title argument.  Any other ideas for
a way to get a title added to the matplot?

> matplot(pm(BucBlAfBatch,"31962_at"),type="l",xlab="Probe No.",ylab="PM
Probe Intensity",(title(main="31962")))
Error in title(main = "31962") : plot.new has not been called yet
