Notice that the new 'nb.reloc' is lacking the last relocation of the
input ltraj. The argument 'addbit' is irrelevant, since type="time".
Am I missing something?

Hi,
I noticed that as.ltraj() reorders the id's alphanumerically. However,
I'd like to keep the order in the input data.frame or
SpatialPointsDataFrame for plotting purposes. Is there some way to
achieve that, except for manipulating the structure of the ltraj object?
Thanks,

Hi,
In ?kernelUD, the "grid" argument is described as:

grid: a number giving the size of the grid on which the UD should
be estimated. Alternatively, this parameter may be an object

Hi,
Before adehabitat was split, I used the function asc2spixdf() to convert
the estimated UD to SpatialGridDataFrame. I see that there's a
estUDm2spixdf() to convert it to SpatialPixelsDataFrame. Should the
coercion to SpatialGridDataFrame be done separately in sp?

Hi,
The problem of estimating a utilization distribution for a group of
animals, based on movement trajectories from each individual is a
complex one. Differences in the duration and frequency of locations of
individual tracks from multiple animals should be accounted for when
calculating such a

In general, I would not choose a book to learn basic statistics based on
whether it has R content or not. What's important is to learn the
concepts. Learning how to use them in a particular software is useful,
but secondary. If we're careless about this distinction, we risk
falling into habits p
