Others may propose more elegant solutions but, in windows one quick an dirty
option would be to change the argument 'pin' and 'fin' within par to get an
image of exactly 1 inch (2.54 cm) i.e.
y <- c(40, 46, 39, 44, 23, 36, 70, 39, 30, 73, 53, 74)
x <- c(6, 4, 3, 6, 1, 5, 6, 2, 1, 8, 4, 6)
par(pin=c(1,1), fin=c(1,1))
plot(x, y, xlab="", ylab="")
abline(h=mean(y), col="red")
#Save the plot in bmp format
savePlot("myplot", "bmp")
and then manually crop the picture using your favorite picture package or
even within a word processor.
I hope this helps
