[R-sig-Geo] PolySet2SpatialPolygons: ring not closed

[Agustin Lobo]

I do:

 > a <- (joinPolys(SpatialPolygons2PolySet(x), 		 
SpatialPolygons2PolySet(absUTMpolysHABS2)))
 > str(a,max.level=2)
Classes ‘PolySet’ and 'data.frame':     506 obs. of  5 variables:
  $ PID: int  5 5 5 5 5 5 5 5 5 5 ...
  $ SID: int  1 1 1 1 1 1 1 1 1 1 ...
  $ POS: int  1 2 3 4 5 6 7 8 9 10 ...
  $ X  : num  418438 418452 418452 418452 418451 ...
  $ Y  : num  4591484 4591478 4591477 4591477 4591476 ...
  - attr(*, "projection")= chr "UTM"
  - attr(*, "zone")= int 31

 > ab <- PolySet2SpatialPolygons(a)
Error in validityMethod(object) : ring not closed

any way to clarify this error? plotMap(a) seems correct.

Thanks

Agus
