[R] image problem in 2.13.1

[Matthias Gondan]

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
