R help - Dec 2008 - Multpile (45x8) graphs of the same page / device: titles crammed

Dear R users,

I'm trying to plot 45x8 graphs on the same pdf / device for the sake
of visual comparison.
par(mfcol=c(45,8))
par(mai=c(0,0,0,0))

In ?title, I can see there are cex and font settings: I set cex = 0.01
and font = 1: it is still very large, and then I tried setting font <
1, e.g. font = 0.5, Then I get an error:

Error in title(paste(Ppercent, "% ", "t30v2msa1.data",
sep=""), cex = 0.1, :
      invalid value specified for graphical parameter "font"

Is there a work around so that I can see all the title?
At the moment, if I set the title to font=1, the upper halves of the
fonts / letters of all the title will be cut, so I can't see the
"Ppercent"...

Thanks!

Regards,

      John

Hi,

"font" should be an integer as described in ?par. I think you want to
play with cex.main (possibly cex in combination, depending on what  
your are plotting)

> dev.off()

Hope this helps,

font is an integer number (1,2,3,4,5 on that device): please do read ?par.

You are looking of 'pointsize': see ?pdf, but I think rather that you 
should use a larger plotting surface (see 'height' and 'width')
