getVolumeUD {move}

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)
