Dear R people, On my freshly installed R-2.13.1 (winxp), the following code yields unsatisfactory results (irregular grid lines instead of a smooth plane): image(matrix(1, nrow=100, ncol=100)) This is working fine, image(matrix(1, nrow=100, ncol=100), useRaster=TRUE) but then right-click and "save as metafile" causes a segmentation fault. Everything worked fine on 2.13.0 Best wishes, Matthias --
