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)
x <- seq(0, 10)
pdf(width=8, height=20)
par(mfrow=c(45, 8), mai=c(0,0.1,0.1,0))
sapply(1:(45*8), function(ii) {
plot(x, rnorm(x))
title(paste("test", ii), cex.main=0.5)
}) -> b.quiet
dev.off()
Hope this helps,
baptiste

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
