[R-sig-Geo] [R-sig-geo] bugs in plotting line segments

[Adrian.Baddeley at csiro.au]

Mathieu Rajerison and Michael Sumner reported two bugs arising when a pattern of line segments is plotted.
Mike traced the bugs to spatstat:::plot.psp and spatstat:::pointsOnLines. Errors occurred if a mark value was NA or if a segment had zero length. 

These bugs have been fixed in the latest release of spatstat, 1.23-5, released yesterday. 

Special thanks to Mike for troubleshooting.
