Hi Guys

Thanks for this!  As I am a beginner, I bet I'm running into some really
basic problems.  Using the example from the Map2poly function in
maptools:

try <- read.shape("euadmll.shp")
mappolys <-  Map2poly(try)
# this produces 14 warnings() of the type:
# 1: level 2 circularity at 62 in: .mtlbuild(.mtafters(r1), rD) # etc #
14: From next release, default hole handling will change in:
Map2poly(try) 
plot(mappolys)

Gives an error:
Error in plot.polylist(mappolys) : malformed plot order

I also get this with Map2ploy(..., raw=FALSE)

I have no idea what this means! :-(

Mick
