Issues importing error ellipses with trilateralized data

[steveh...@gmail.com]

Hi Chris,

I am trying to import location data estimated from a UHF node array. I used a similar trilaterization method as described in this discussion. I created the Argos.semi.major, Argos.semi.minor, and Argos.orientation columns using the methods from code from that conversation.

When I try to import using as.telemetry() I get the following error:

Error in `$<-.data.frame`(`*tmp*`, "COV.minor", value = numeric(0)) : replacement has 0 rows, data has 220

When I remove the Argos columns, I can successfully import the data.

I've attached code and data that replicates the issue on my machine (using the Github package and R 4.4.1).

Thanks!

Steve

Hi Steve,

You are selecting 'Argos.semi.major' twice. If you change one of them to 'Argos.semi.minor' in select() then as.telemetry() will run.

Cheers,

Ah thanks for noticing that!

I changed it, but I still get an error: Error in `[[<-.data.frame`(`*tmp*`, DOP.LIST$horizontal$VAR, value = numeric(0)) :

  replacement has 0 rows, data has 220

So it looks like this was an issue with the github version of ctmm (1.2.1). 

The code works as intended for the CRAN version of the package (1.2.0).
