getVolumeUD: Utilization distribution (UD)

In move: Visualizing and Analyzing Animal Track Data

Utilization distribution (UD)

Description

The UD represents the minimum area in which an animal has some specified probability of being located (Cumulative Distribution Function).

Usage

  ## S4 method for signature '.UD'
getVolumeUD(x, ...)

Arguments

x	a DBBMM, DBBMMStack, dynBGB, .UD or .UDStack object
...	when x is of class DBBMM or dynBGB, several objects of class DBBMM or dynBGB can be added (see 'Examples')

Value

'raster' or 'rasterStack'
If several objects are provided, a list of rasters is returned

Note

To obtain this modified UD raster from a DBBMMBurstStack object, transform the object with the UDStack function into a '.UDStack' class, and than use the getVolumeUD function upon the obtained object.

Examples

data(leroydbbmm)
data(dbbmmstack)
data(leroydbgb)
getVolumeUD(leroydbbmm) # for a DBBMM object
getVolumeUD(dbbmmstack) # for a DBBMMStack object 
getVolumeUD(leroydbgb) # for a dynBGB object 

getVolumeUD(leroydbbmm, leroydbgb) # for several objects 

plot(getVolumeUD(leroydbbmm))

## e.g. select the raster corresponding to the 95% UD
leroyUD <- getVolumeUD(leroydbbmm)
leroyUD[leroyUD>0.95] <- NA
plot(leroyUD)
