I want eps for latex. Png not enabled in my installation of R.
Conversion to eps was good with imagemagick, poor with gimp.

The image was blank, on my screen a small window about 50 mm each side
(using imagemagick. In gimp, error dialogue window received, unable to
open file). This did not occur when I used gimp and imagemagick.

This command created a small blank eps file.
