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. ----- Tony Fischbach, Wildlife Biologist Walrus Research Program Alaska Science Center U.S. Geological Survey 4210 University Drive Anchorage, AK 99508-4650 AFischbach at usgs.gov http://alaska.usgs.gov/science/biology/walrus -- View this message in context: http://r-sig-geo.2731867.n2.nabble.com/Coerce-spatialPolygons-to-spatialLines-tp6794570p6794570.html Sent from the R-sig-geo mailing list archive at Nabble.com.
