Warnings when using 1 calibration period (no model ageing)?

[Louise de Raad]

I have a number of tags that stopped working (at an unknown location) at some point, before the bird returned and the tag was retrieved. I have changed the Calibration.periods as follows:

 

> Calibration.periods<-data.frame(
+ calibration.start=as.POSIXct(NA), # start of the second calibration period
+ calibration.stop=as.POSIXct(c("2013-08-05", NA)), # end of the first calibration period
+ lon=-4.37, lat=58.38)

> print(Calibration.periods)
calibration.start calibration.stop lon lat
1 <NA> 2013-08-05 -4.37 58.38
2 <NA> <NA> -4.37 58.38

 

and removed the model.ageing part from the make.calibration function:

> Calibration<-make.calibration(Proc.data, Calibration.periods, model.ageing = FALSE)
dusk 191 was excluded from the calibration
calibration method used: parametric.slope
likelihood correction switched to TRUE
dusk 189 was excluded from the calibration
calibration method used: parametric.slope
dusk 188 was excluded from the calibration
calibration method used: parametric.slope
estimating correction function...
There were 50 or more warnings (use warnings() to see the first 50)

 

This resulted in loads of warnings (see below). Is this normal, do I just proceed? What do they mean?

  Hi Louise,

 You should have deleted second NA, something like:

Calibration.periods<-data.frame(
 calibration.start=NA, # start of the second calibration period
 calibration.stop=as.POSIXct("2013-08-05") # end of the first calibration period
 lon=-4.37, lat=58.38)

Cheers,

  Eldar
