When I run the example in R 1.6.2, and view it with gs, I get a good plot. When I run the example in R 1.7.0, and view it with gs, I get a bad plot. (run on the same host) My "bad plot" is as described by Stephen.

(followed by ~200000 lines of the same type, with slowly changing values) In the "bad" postscript file, at about the same point in the file, is this: %%EndProlog %%Page: 1 1 bp 77.04 91.44 743.76 534.96 cl 0 0 0 rgb 0.75 setlinewidth [] 0 setdash np 101.73 313.20 m 0.00 0.01 l 0.00 0.01 l 0.00 0.01 l 0.00 0.01 l 0.00 0.01 l (followed by ~200000 lines, including some like these)
Confirmed on RedHat Linux 8.0. Filing as bug report. (An old version of Splus had a similar bug: If you want to use rlineto, you need to round *before* differencing.)
