adehabitat version 1.4
Dear all,
I have just uploaded to CRAN the version 1.4 of the
package 'adehabitat'. Significant changes are
listed below:
- The eigenanalysis of selection ratios (Calenge and Dufour, 2006, Ecology)
can now be performed using the function eisera(). It can be used for
the analysis of
habitat selection when habitat can be considered to consist of several
habitat types

burst argument in as.ltraj()
Hi. I am running the as.ltraj () function in adehabitat (v 1.4 under R 2.2.1)
but can't seem to correctly specify the burst argument. i.e., the ltraj
object returned consists of only one component, when in fact my data consist
of more than one burst of reloctions per animal. i've set up the data (xy,
date, id, burst) in list form following the example given in ?as.ltraj. to

Trouble with first passage time analysis using adehabitatLT
Hey all,
I've run into a few problems running first passage time analysis. I'm hoping
someone might be able to help me sort this out. I'm fine up to the point of
creating the ltraj object from a dataset.
/test<-read.table("~/Desktop/R_Directory/test.txt",header=TRUE)

Compatibility issue between lme4 and kml (operateur "[")
Hi all,
There is a compatibility issue between the package 'lme4' and my package
'kml'. I define the "[" operator. It works just fine in my package (1). If I
try to use the lme4 package, then it does no longer work (2). Moreover, it
has some kind of strange behavior (3). Do you know what is wrong? Any idea
of how I can correct that?
Thanks for your help

Help with iteration using while loop
Hello everyone,
I am trying to use while loop to iterate a function until convergence. But I
am having problem when I try to use a fixed number of iterations.
Say I want to use maximum iteration of 150. If the value don't converge
within maximum iteration, show warning of no convergence.
Currently I don't have non- convergence problem so I think my code works
fine. But in future I may
