How about this:
in2mm<-25.4 # scale factor to convert inches to mm
pdf("test.pdf",width=8.3,height=11.7)
pin<-par("pin")
plot(c(0,pin[1]*in2mm),c(0,pin[2]*in2mm), type="n", xaxs="i", yaxs="i")
lines(c(10,10),c(0,10))
text(11,5,"1 cm", adj=0)
lines(c(0,40),c(20,20))
text(20,24,"4 cm")
polygon(c(50,50,70,70),c(50,70,70,50))
text(60,60,"2x2 cm")
dev.off()
cheers
