<div> </div>
<div>I wonder if there already exists a solution on how to combine UDs.</div>
<div> </div>
<div>My intention is to create a reference UD for Mon, Tue, ...., Sun - thus, 7 reference UDs.</div>
<div>Hence, I compute for each Monday within my data the Brownian bridge home range.</div>
<div>I do not use the byburst function because I use different grid parameters.</div>
<div>Then I would like to (maybe) average all the estimated UDs for Mondays and create one single estUD or SpatialPixelsDataFrame.</div>
<div>(To recreate an estUD would be awesome because then I could use getverticeshr to estimate the home range.)</div>
<div> </div>
<div>I tried to figure out an example:</div>
<div> </div>
<div>
<div>library(adehabitatHR)<br/>
library(maptools)</div>
<div>data(puechcirc)</div>
<div><br/>
dOne<-puechcirc[1]<br/>
dTwo<-puechcirc[2]</div>
<div>tata1<-kernelbb(dOne, sig1=6.23, sig2=58, grid=50)<br/>
tata2<-kernelbb(dTwo, sig1=3.72, sig2=58, grid=80)</div>
<div> </div>
<div>The goal should be to generate an extended averaged UD out of the two.</div>
<div>I've already tried spRbind but of course it just returned the positions but not the data within the pixels.</div>
<div>I also think that the different grid cell size could be challenging but for my data I have not find a better way</div>
<div>to achieve ~50 meters cell size than to align the grid parameter on the data.</div>
<div> </div>
<div>I would appreciate any help :)</div>
<div>Best, Ena</div>
<div> </div>
<div>(Of course I will send you the solution if I find one)</div>
