[R-sig-Geo] maptools/kmlPolygons not outputting all Polygon objects

[Tomislav Hengl]

I've tried creating a KML file using the plotKML package and I did not 
notice anything strange with Alaska:

 > data(wrld_simpl)
 > library(plotKML)
plotKML version 0.4-5 (2014-07-30)
URL: http://plotkml.r-forge.r-project.org/
 > kml(wrld_simpl, colour=NAME)

You can write KML file anyway you prefer also directly by using the XML 
package (and by using the "base::sprintf" command as in 
https://r-forge.r-project.org/scm/viewvc.php/pkg/R/layer.SpatialPolygons.R?view=markup&root=plotkml).

HTH,
