Thanks. I upgraded to R 2.8.1 and tried tiff(filename = "volc.tif", width=600, height=400, compression = "none", bg = "white", res = 300) image(t(volcano)[ncol(volcano):1,]) dev.off() but this produces error Error in plot.new() : figure margins too large How this should be modified to produce a decent-sized graph?
Well, thae is a 2" by 1.3" image, so the pointsize is way too large.
Increase the dimensions or decrease the resolution or decreaase the
pointsize.
(As a warning, there was a 'grid' bug that affected some versions of
tiff, png etc in 2.8.0 and 2.8.1 when plotting lattice plots at
non-default resolutions. The NEWS item is
o grid-based plots no longer reset the base text size to the
default 96dpi in cairo-based bitmap devices.
for 2.8.1 patched. But that produces too small not too large text.)

Hello, How to produce .tif graphic in colors using bitmap function? e.g this produces figure in grayscale bitmap(file="volc.tif", type = "tifflzw", res = 300) image(t(volcano)[ncol(volcano):1,]) dev.off()
Why not upgrade R and use the tiff() device? Uwe Ligges
I'm using Windows XP and ghostscript.
