locatePolygonPoints2: Point to Polygon Locator 2

In kaiyaprovost/subsppLabelR: Subspecies Labeled Occurences Generator

Point to Polygon Locator 2

Description

This function takes a one polygon and a list of points and determines whether the points fall within the polygon, then adds a column for each polygon's name with a boolean of whether the point overlaps.

Usage

locatePolygonPoints2(
  test_points,
  polygonA,
  crs = "+proj=longlat +ellps=WGS84",
  setcoord = TRUE,
  nameA = "A"
)

Arguments

test_points	The points to check where they fall
polygonA	The polygon
crs	A coordinate reference system to assign to the polygons and the test points if setcoord = TRUE
setcoord	Whether to set a coordinate reference system to the points and polygons
nameA	The (subspecies) name associated with the first polygon

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)
densPol_sin = densityMapToPolygons(densityMap=dens_sin)
densPol_ful = densityMapToPolygons(densityMap=dens_ful)
polyLocations = labeledLoc
polyLocations = locatePolygonPoints2(test_points=polyLocations,polygonA=densPol_sin,
   crs="+proj=longlat +ellps=WGS84",setcoord = TRUE,nameA="sinuatus")
