First off, thanks so much for all your assistance so far!
I've been working on incorporating both the VHF and GPS logger telemetry sets into HR analysis. I fit uere models from stationary loggers to assign to the GPS logger data and I assign a constant value for the uere of the VHF telemetry.
However, when I attempt to combine the two telemetry objects with tbind(), I get this error:
Error in `$<-.data.frame`(S3Part(x, TRUE), name, value) :
replacement has 0 rows, data has 644
This error does not occur when I don't assign the telemetry objects an uere model, so I assume having two different error structures are causing an issue combining the telemetry objects.
