Error in validityMethod(as(object, superClass))

[AlbertoPina4]

Hi,

I'm trying to use my own animal tracking data (.csv) through the 'move' package but I am having the following error message when I tried to use the "move" function with a data.frame containing tracks from different individuals (5 to be exact). I previously ran the example shown in the manual for a single individual and had no problems.

This is my data.frame

Rabis_moveVis.csv

Previously for this df I had the individuals in disorder, i.e. I inserted the individuals' tracks in the df randomly and the following error appeared:

Error in validityMethod(as(object, superClass)) : 
  The data in the MoveStack object are not grouped per individual

After that, I arranged the tracks in the df according to the timestamps (.csv that I attached to this message) and the following error appeared:

Error in validityMethod(as(object, superClass)) : 
  Not ordered timestamps per individual occured

Could you please advise me on what might be wrong and needs changing. Thanks once again for the package.
