I think I set the color of the polygon line "white" which is the KML
default, so you can only change the color of polygons (fill); see:
To change colors per polygon you should run:
legend = get("colour_scale_factor", envir = plotKML.opts)
kml_layer(eberg_zones, colour=ZONES, colour_scale=legend)
See also: http://gsif.isric.org/doku.php/wiki:tutorial_plotkml
could also be changed but not via plotKML.
