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<-as.POSIXct("2015-06-28", tz="GMT")
end<-as.POSIXct("2016-05-29", tz="GMT")
 
Proc.data<-get.tags.data("TAGS_024_2015_SWTH_000-b.csv", start.date=start, end.date=end)
 
Calibration.periods<-data.frame(calibration.start=as.POSIXct(c(NA,"2015-06-28"), tz="GMT"),
                                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<-make.calibration(Proc.data, Calibration.periods, likelihood.correction = FALSE)

Try removing "NA" as follows

 

 

 

Calibration.periods<-data.frame(calibration.start = as.POSIXct(c("2015-06-28"), tz="GMT"),
                                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?
