UDStack: Creating UDStack objects

In move: Visualizing and Analyzing Animal Track Data

Creating UDStack objects

Description

The function enables the easy generation of .UDStacks, which is for example useful for using other UD function such as getVolumeUD.

Usage

UDStack(x,...)

Arguments

x	A list of rasters, a rasterBrick, a rasterStack or a DBBMMBurstStack object that needs to be converted to a .UDStack object.
...	Currently not used

Details

The values of a DBBMMBurstStack are standardized per raster layer.

Value

An UDStack object

Examples

data(dbbmmstack)
stk<-as(dbbmmstack,"RasterStack")
UDStack(stk)
lst<-split(dbbmmstack)
UDStack(lst)

## transforming a DBBMMBurstStack into UDStack, e.g. to than 
## use the "getVolumeUD" or "emd" function
data(leroy)
leroyB <- burst(x=leroy,f=c(rep(c("Behav.1","Behav.2"),each=400),rep("Behav.1", 118)))
leroyBdbb <- brownian.bridge.dyn(object=spTransform(leroyB[785:820], center=TRUE), 
                                 location.error=12, dimSize=115, ext=.45, 
                                 time.step=25/15, margin=15)
cellStats(leroyBdbb, sum)
leroyBud <- UDStack(leroyBdbb)
cellStats(leroyBud, sum)
