detectionHistory: Error: $ operator is invalid for atomic vectors

[lepa...@gmail.com]

Dear group,

I´m trying to construct the detection history of a camera trap data set already in an excel/csv file, but I get this error when trying the "detectionHistory" function:

Error: $ operator is invalid for atomic vectors
In addition: Warning message:
timeZone is not specified. Assuming UTC

This is not the first time I used this code, and with other files it has worked in the past, but haven´t been able to make this one work. I am sure my input data is a dataframe (recordTable) and a matrix for CamOp, so not sure what atomic vector is this refering to.

Can anyone point me in the right direction to solve this issue?

Thank you very much in advanced

Hi Lain,

would you mind sharing the code you used and a reproducible example please? It's easiest with an R workspace. You can subset to only a few records and stations, just make sure the error occurs. Also, are you using the recent CRAN version?

The error suggests there is the function tries to access a column of a data frame (via $), but the object is a vector and not a data frame. It is a bug, but I can't tell what exactly goes wrong without seeing the data.

Best regards,

Jürgen
