converting to telemetry object

[Sophie Zawadzka]

Hi there,

I am currently having trouble trying to convert a .csv dataset into a telemetry object using the as.telemetry() command. I have modified the dataset to use the Movebank naming conventionsn and format, however when I try to convert I get the warning messages: 

"1: In telemetry.clean(telist[[i]], id = id[i]) : 

Times might be out of order or duplicated in (dataset). Make sure that timeformat and timezone are correctly specified.

2: In telemetry.clean(telist[[i]], id = id[i]) : 

Duplicate times in (dataset). Data cannot be fit without error model."

Am I right in thinking I will need to fit an error model for the dataset? and if so, do you recommend any help pages that would help me understand how to go about it?

Many thanks,

Sophie

Hi Sophie,

If you have multiple locations recorded at the same time, then are you sure that's right? I would check that the timestamp format is correct and that the duplicates aren't erroneous.

But if that's the data, then you would need a location error model to capture that variance. See vignette('error'): https://cran.r-project.org/web/packages/ctmm/vignettes/error.html

Best,

Chris
