trimPolygonsByOverlap: Remove Overlapping Polygons

In kaiyaprovost/subsppLabelR: Subspecies Labeled Occurences Generator

Remove Overlapping Polygons

Description

This function takes polygon features flagged for removal from flagPolygonOverlap() and removes them from the polygon. Called within polygonTrimmer().

Usage

trimPolygonsByOverlap(polygon, idList = NULL, intList = NULL)

Arguments

polygon	Polygon to remove flagged features from.
idList	List of flagged features to completely remove.
intList	List of intersections to remove.

Examples

listFromSubspeciesOcc = subspeciesOccQuery(spp="Cardinalis sinuatus",
   subsppList=c("sinuatus","peninsulae","fulvescens"),pointLimit=100,
   dbToQuery="gbif")
labeledLoc = labelSubspecies(subsppOccList=listFromSubspeciesOcc)
locs = labeledLoc[labeledLoc$subspecies=="sinuatus",]
locs_sin = labeledLoc[labeledLoc$subspecies=="sinuatus",]
locs_ful = labeledLoc[labeledLoc$subspecies=="fulvescens",]
dens_sin = subspeciesDensityMap(localities=locs_sin,quant=0.95,
   xmin=-125,xmax=-60,ymin=10,ymax=50)
dens_ful = subspeciesDensityMap(localities=locs_ful,quant=0.95,
   xmin=-125,xmax=-60,ymin=10,ymax=50)
