FlightR calibration error

Question

I'm working on calibrating some data in FlightR but I keep getting an error with the "make.calibration" object and am not sure how to fix it? 

 

The error is:

 

Error in Twilight.time.mat.Calib.dawn[-25, ] : 

  incorrect number of dimensions
 
 

Here is my code: 

 

start
end
 
Proc.data
 
Calibration.periods
                                calibration.stop=as.POSIXct(c("2016-05-29", NA), tz="GMT"),
                                lon=-148.80441, lat=63.6520)
 
print(Calibration.periods)
 
# create a calibration object 
 
Calibration

Try removing "NA" as follows

 

 

 

Calibration.periods
                                calibration.stop = as.POSIXct(c("2016-05-29"), tz="GMT"),
                                lon=-148.80441, lat=63.6520)
 
 
But your dates look wrong. Are you sure you want to add a year's worth of calibration data?

Can you let me know how you solved this error?

 

I'm getting the same thing while trying to calibrate my data:

 

Calibration.periods
                                calibration.stop=as.POSIXct("2014-07-11"),
                                lon=-64.3431, lat=45.8980) #works fine
 
calibration.parameters
                                                   model.ageing=F, log.light.borders=log(c(2, 63)), 
                                                   log.irrad.borders=c(-1000, 1000)) #receive error: Error in Twilight.time.mat.Calib.dawn[-25, ] : 
  incorrect number of dimensions
 
 
My data is as follows (I used GeoLight2TAGS to get after defining sunrise/sunsets):
head(TAGSbank066)
                  datetime light twilight interp excluded
1 2013-07-05T12:37:59.000Z    64        0  FALSE    FALSE
2 2013-07-05T12:39:59.000Z    64        0  FALSE    FALSE
3 2013-07-05T12:41:59.000Z     3        0  FALSE    FALSE
4 2013-07-05T12:43:59.000Z     3        0  FALSE    FALSE
5 2013-07-05T12:45:59.000Z     5        0  FALSE    FALSE
6 2013-07-05T12:47:59.000Z     7        0  FALSE    FALSE
