There appears to be unintentional behaviour in the size of the bounding box for
PDF graphics produced with the current R2.4, compared to 2.3.1. I posted two PDF
files, both produced with the same R script below, but different versions of R:

The code is here:


pdf(file=sprintf("test-%s.pdf", version$"svn rev"), width=4, height=4)
par(mai=par("mai")[rep(1:2,2)])
x = seq(0, 10*pi, length=3000)
plot(x*cbind(sin(x),cos(x)), type="l", col="mistyrose", lwd=3)

sink(textConnection("s", "w"))
options(width=40)
print(sessionInfo(), width=30)
sink()

text(-30, 30-4*seq(along=s), s, adj=c(0,0.5), cex=0.7) 
dev.off()



and one of the differences between the resulting PDF files is:
test-38323.pdf: /MediaBox [0 0 288 288]
test-38523.pdf: /MediaBox [0 0 595 841]

The former corresponds to 4x4 inches, the latter to 21cm x 29.67cm.
