Hello everyone!
I have data (in excel) of the camera trap. I would like to classify my records as independent
(i.e., consecutive photos recorded one or more individuals of the same species over a minimum time interval of an hour). How do I do this with CamtrapR?
My data are tabulated in excel this way : 




Thank you very much to all!

Hi Adriane, 
that issue has been brought up a few times before, and there is solution, but it is not readily implemented in camtrapR.
See these threads:

At the moment you'd need to run the internal function assessTemporalIndependence on your record table. Please see the links above for details (there's also a few more threads where that function is mentioned. I am planning to make it a proper standalone function some time, but I haven't gotten around to do it. 
In your table, you'd need to combine the date and time columns with paste() to have a date-time column. 
Also, the approach I just described removes records and gives you a record table containing only the first record of a sequence. 

All in all, it is just a bad workaround because there is no proper function for this yet. Let me know if you have more questions.
Best regards,
Jürgen
