Thank you for your interest. I'm new to R, but pretty enthusiastic
about it. You can find attached the matrix in question. It's a
representation of an optic disc from a retinal photograph.

I noticed that the error occurs only when using the option 'pretty=T'.
Also, it happens in two of about seven or eight similar objects I
played with.
