There remains an embarrassing bug because we have not had time to build some important software. We have an intermediate plot language called vplot. Intermediate plot files can be saved as NAME.v (if reproducible) or as NAME.v.save (if not). When a NAME.ps file is created from a NAME.v.save file, the figure has been reproduced in a disappointingly trivial sense. This problem can be attacked in both cake language and TeX language and we will have the most robust result if we do it both ways. Obviously people will always be able to cheat the [R] [NR] convention, but we don't want people to do so inadvertently.
Unfortunately, this bug was not fixed in time for my paper book so that book nowhere defines the meaning of [R] and [NR]. I hope to fix it in time for the first CD-ROM distribution.
