Subject: Coerce spatialPolygons to spatialLines
I am producing plots of spatialPolygons over a spatialPixelDataFrame
and wish to convert the spatialPolygons object to a spatialLines object
as a work around of two plotting problems.
Problem 1: Donut holes in the polygons are plotting as white,
rather than as a null color that would allow the spatialPixelDataFrame
object's colors to show through.
Problem 2: I wish to set the polygon outline color so that it better
contrasts with the color ramp of the spatialPixelDataFrame object plot.
