UD object.
Rasterize the probability density function "PDF", probability mass function "PMF", or cumulative distribution function "CDF".
telemetry or UD object.
Confidence level of the UD area. I.e., the 50% core home range would be given by level.UD=0.50.
Confidence level for the magnitude of the above area. I.e., the 95% CI of the core home range area.
Character name of file for raster file.
Character format, if not inferred from filename extension (see writeRaster.)
Character name of folder for shapefile.
Character name of files for shapefile.
Optional arguments passed to writeRaster, writeOGR, etc..
raster.UD returns a raster of the maximum likelihood (ML) distribution function DF.
DF=PDF gives the average probability density per cell,
DF=PMF gives the total probability per cell,
and DF=CDF gives the cumulative probability.
SpatialPoints.telemetry returns a single spatialPoints object for the x-y locations, with individual identity information lost.
SpatialPointsDataFrame.telemetry returns a SpatialPointsDataFrame with the individual identities recorded in the data frame.
SpatialPolygonsDataFrame.UD returns a SpatialPolygonsDataFrame of the low, ML, and high home-range area estimates, in the appropriate order for plotting.
writeRaster writes a raster file to disk, with pixel values corresponding to the density function.
writeShapefile writes a shapefile to disk, with UD polygons corresponding to the low, ML, and high home-range area estimates.
