Working with CSV and no photos

[D dpzzp]

Hello, I´m working with phototrapping data but I lack the photos themselves, having only CSV archives that has been extracted with Digikam, my intention is to use activity and overlap after, most information on the topic talks about working from the images. 

How do I work with the CSV data? in which way I have to set up the document (modying it with excel) so it works accordingly in R? this is my first time using the program so I´m a bit lost.

Thanks in advance

Hello, 

yes, you can absolutely work with csvs only in camtrapR and don't need image files. 

You generally need two tables in camtrapR:

1. record table (contains information on animal detections: which species was detected where and when?) - digikam provides something close to this
2. camera trap table (contains information about camera trap setup (station IDs, operation period, additional information about the camera trap locations - digiKam does not provide this, but it may not be needed for your use case (activity)

Please share the structure of your tables, then we can see how to feed them into camtrapR. There are several internal (hidden) functions which access and process information from a digiKam database, these may be needed here. 

Also note that the development version of camtrapR on GitHub contains a Shiny dashboard which can ingest csv tables and then provides a code-free environment for analysis. Might be worth a look since you're new to camtrapR (and especially if you're new to R also). It requires the camera trap table though. 

In any case, the first step would be to see your tables. Ideally call:

str(yourtable) 

in R and share the output, or provide a short (few lines) sample of your tables as csv.

Thank you and best regards,

Jürgen
