[R-sig-Geo] Rediscretising trajectories in adehabitatLT

[Bronwyn Hradsky]

Dear list members,

 

Do you know how to prevent redisltraj (type = "time") in adehabitatLT
(version 0.3.16) from removing the last location from each burst when
rediscretising?  I noticed this with my data and also in the example
provided in the help file.

 

I would like to rediscretise within specific bursts and then bind the bursts
back together, so I don't want to lose the final location from each burst. 

Is there some way of preventing this?

 

e.g. I have GPS fixes at 30 min intervals with some fixes missing.  For one
burst, the final fix was successful and occurred at  2014-05-17 17:00:00.  I
rediscretise using

 

> vulpes.added <- redisltraj(vulpes.chop, 1800, type = "time")

 

which works well in terms of interpolating the missing fixes.  However, the
final fix for the burst is now 2014-05-17 16:30:00

 

Many thanks,

Bronwyn
