Thanks Prof Ripley, now I understood. tiff(filename = "volc.tif", width=600, height=400, compression = "none", bg = "white", res = 300, pointsize=3) par(mar=c(3,3,2,2), cex=1) image(t(volcano)[ncol(volcano):1,], xaxt="n", yaxt="n") axis(1, at=seq(0, 1, 0.1), cex.axis=0.8, tick=T) axis(2, at=seq(0, 1, 0.1), cex.axis=0.8, tick=T) dev.off()
