as.telemetry error (New user)

[Malakhi Spint]

Hey all,

I'm practically completely new to R and the ctmm package. I'm trying to use it to find outliers in my data. When I use package, when I try to use as.telemetry it gives me an error "Error in `$<-.data.frame`(`*tmp*`, "id", value = c(1L, 1L, 1L, 1L, 1L, :

replacement has 5505 rows, data has 0"

I don't know why it says there is no data. I would love to get some expert opinions.

Thanks!

Hi Malakhi,

If you do str(name_of_data.frame), what does the result look like? This is related to the structure of your data.

Hey Jesse,

This is the sample that the str() brings. I've been trying to format it correctly ever since and have still had the issue.

'data.frame': 5046 obs. of 16 variables: $ animal.id : int 40879 40879 40879 40879 40879 40879 40879 40879 40879 40879 ... $ timestamp.utc : chr "2023-11-28 7:00 PM" "2023-11-28 6:00 PM" "2023-11-28 5:00 PM" "2023-11-26 9:16 PM" ... $ timestamp.lmt : chr "2023-11-28 12:00:11-07:00" "2023-11-28 11:00:40-07:00" "2023-11-28 10:00:11-07:00" "2023-11-26 14:16:32-07:00" ... $ timestamp.scts.utc : chr "2023-11-28 8:03 PM" "2023-11-28 8:03 PM" "2023-11-28 8:03 PM" "2023-11-26 9:17 PM" ... $ timestamp.scts.lmt : chr "2023-11-28 13:03:04-07:00" "2023-11-28 13:03:04-07:00" "2023-11-28 13:03:04-07:00" "2023-11-26 14:17:04-07:00" ... $ manufacturer.name : chr "Iridium" "Iridium" "Iridium" "Iridium" ... $ reciever.latitude : num 46.8 46.8 46.8 46.8 46.8 ... $ receiver.longitude : num -114 -114 -114 -114 -114 ... $ height.above.mean.sea.level: int 1492 1487 1484 1490 1485 1492 1472 1474 1481 1476 ... $ GPS.DOP : num 2.4 2.6 5.6 4.4 4 2.4 3 2.2 2.6 4.4 ... $ GPS.fix.type : chr "3" "3" "3" "3" ... $ mortality.status : chr "Nothing Detected" "Nothing Detected" "Nothing Detected" "Nothing Detected" ... $ external_temp : int 7 5 5 10 11 15 10 9 7 4 ... $ voltage.resolution : num 3.28 3.28 3.36 3.28 3.28 3.28 3.36 3.28 3.28 3.36 ... $ beacon.frequency : num 3.6 3.6 3.6 3.6 3.6 3.6 3.6 3.6 3.6 3.6 ... $ animal.nickname : chr "Animal with Collar 40879" "Animal with Collar 40879" "Animal with Collar 40879" "Animal with Collar 40879" ...

Hi Malakhi,

You need to rename your relevant timestamp, latitude, and longitude columns (timestamp.utc, receiver.latitude, and receiver.longitude?) according to Movebank conventions, or at least simpler names. Chris has done a lot of work to allow ctmm to automatically detect and reformat relevant data, but he can’t code in every possible option.

Thank you for your responses! They are named according to the Movebank Attribute page, but I have changed them and still no dice. I've also tried the ctmm.shiny as well and get an error hoping it may tell me more.

Thank you for your help!

Hi Malakhi,

Can you paste what head() returns on the data.frame?

Best,

Chris

Hey Chris,

Sorry for the late response. I just had to reformat multiple times and I ended up getting it to work!

Best-
