[R] trouble with maps

[Deborah Swayne]

Has anyone else seen this behavior from the "maps" package?
    
map('state', fill=TRUE)

results in a lively mix of overlapping polygons inside a
map of the US, but they have no obvious relationship to
state boundaries.  (See attached jpeg.)

I reinstalled the maps and mapdata packages from
   ftp://ftp.mcs.vuw.ac.nz/pub/statistics/map/  
to see it that would help, but it doesn't.

Since our platform is an SGI (running R-1.8.0, development
version, June 25), I made sure to use mapget.c.notlinux,  
and that didn't help either.

Any thoughts?  Is there something I'm missing?
