[R-sig-Geo] Problems Plotting GeoTIFF

[Edzer Pebesma]

Although I can't reproduce the problem on my Ubuntu laptop,

https://stat.ethz.ch/pipermail/r-help/2011-July/283568.html

suggests 2.13.1 introduced a problem with image(), which is out of "our"
hands (ie. cannot be fixed by the developers of spatial packages)

Let me know if you see this differently,
