outerProbability: Calculates the probabilities at the edges of a raster

In move: Visualizing and Analyzing Animal Track Data

Description

The outerProbability method calculates the summed probability of the cells at the border of a raster

Usage

  ## S4 method for signature 'RasterLayer'
outerProbability(raster,border,...)
  ## S4 method for signature 'DBBMMStack'
outerProbability(raster,border,...)

Arguments

raster	a RasterLayer or DBBMMStack object that has values for the raster cells
border	numeric from 0 to 1; ratio of the number of columns at the border relative to the whole raster from which the probabilities should be summed up; default is 10% (0.1)
...	hand over information

Details

The function returns the summed probability at the border (e.g. the outer 10% of the cells) of a raster. This value can be used as an indicator whether the extent of the used raster is to small for the UD calculation and therefore too much probabilities are not calculated because they are outside the raster.

Value

numeric value for a single DBBMM object, or a list of numeric values for a DBBMMStack

Examples

data(leroydbbmm)
#calculate the probabilities of 20% of the raster at the border from a DBBMM
outerProbability(leroydbbmm, border=.2)

#calculate the probabilities of 50% of the raster at the border from a DBBMMStack
outerProbability(leroydbbmm, border=.5)
