[R] Multpile (45x8) graphs of the same page / device: titles crammed

[tsunhin wong]

What if cex=0.001 with font=1 will still have the title font too
large? (so that the upper halves of title is cut off and cannot be
seen?)
Will there be a workaround? Can there be a work around so that I can
label each small graphs with the info I need in a "smaller" way?
Thanks!

Regards,

      John
