ctmm (version 0.3.0)

export: Export ctmm data formats

Description

Functions to export ctmm data formats into common sp, raster, and ESRI formats.

Usage

raster.UD(UD,DF="CDF",CI="ML")

SpatialPoints.telemetry(data)

SpatialPolygonsDataFrame.UD(UD,level.UD=0.95)

writeShapefile.UD(UD,folder,file=UD@info$identity,level.UD=0.95,...)

Arguments

UD
UD object.
DF
Rasterize the probability density function "PDF" or cumulative distribution function "CDF".
CI
Which confidence interval of the bandwidth uncertainty to use: the "ML" point estimate, "low" or "high".
data
telemetry data object.
level.UD
Confidence level of the UD area. I.e., the 50% core home range would be given by level.UD=0.50.
folder
Character name of folder for shapefile.
file
Character name of files for shapefile.
...
Optional arguments passed to writeOGR.

Value

  • raster.UD returns a raster of the maximum likelihood (ML) probability density function. SpatialPoints.telemetry returns a spatialPoints object for the x-y locations. SpatialPolygonsDataFrame.UD returns a SpatialPolygonsDataFrame of the low, ML, and high optimal-bandwidth AKDE home-range areas, in the appropriate order for plotting.

Details

writeShapefile.UD writes a shapefile to disk, with polygons corresponding to the low, ML, and high optimal-bandwidth AKDE home-range areas.
