Hi folks,
What is the best way to deal with this problem? I'm working through the camtrapR
vingette 1. I've created my photo directory using the function createStationFolders. But 2 of my cameras did not collect any photos. Now I'm down to timeShiftImages and I have a circular set of errors that there are no  .JPG_original files or if I delete the folder that does not contain any images then  Error: Station directory does not exist:
Do I need to go back to the beginning and remove the dud camera from the directory?
Thanks,
Cheryl

Please check parameter "undo" and make sure you want it to be TRUE.
It should be FALSE when you first run is. Undo is for reverting to the original images only
