Hi,
I'm having trouble understanding why the following call to redisltraj()
with u=1 doesn't return the full input ltraj object (adehabitatLT):
---<--------------------cut here---------------start------------------->---
R> n <- 51
R> (crw <- simm.crw(date=seq(n), r=0.5))
*********** List of class ltraj ***********
Type of the traject: Type II (time recorded)
Regular traject. Time lag between two locs: 1 seconds
Characteristics of the bursts:
id burst nb.reloc NAs date.begin date.end
1 A1 A1 51 0 1969-12-31 18:00:01 1969-12-31 18:00:51
infolocs provided. The following variables are available:
[1] "pkey"
R> redisltraj(crw, 1, type="time", samplex0=TRUE)
*********** List of class ltraj ***********
Type of the traject: Type II (time recorded)

---<--------------------cut here---------------end--------------------->---
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?
Cheers,
