subspeciesDensityMap: Generate Subspecies Density Maps

In kaiyaprovost/subsppLabelR: Subspecies Labeled Occurences Generator

Generate Subspecies Density Maps

Usage

subspeciesDensityMap(
  localities,
  quant = 0.95,
  xmin = NULL,
  xmax = NULL,
  ymin = NULL,
  ymax = NULL,
  total_range
)

Arguments

localities	Labeled localities as generated from labelSubspecies() or subspeciesOccQuery()
quant	quant for density, below which points are removed. E.g., if set to 0.95, removes 95 \item xminMinimum longitude extent to clip to \item xmaxMaximum longitude extent to clip to \item yminMinimum latitute extent to clip to \item ymaxMaximum latitude extent to clip to

This function uses 2D kernel density estimation to make a density raster of points for each subspecies. It then removes all but the most dense cells as definied by quant.

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