Usage

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

Value

'raster' or 'rasterStack'

If several objects are provided, a list of rasters is returned

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)
