auk_zerofill error message when following "eBird Best Practices" Cornell doc

[paulauvirage]

Hello

I am following the example for data import and creation of a zerofill data.frame in R

in 2.3 with code

ebd_zf <- auk_zerofill(f_ebd, f_sampling, collapse = TRUE)`

and failing with the message

Error:%in%(x = group_id, table = names(x)) is not TRUE

I am using R 4.0.1 in R Studio 1.3.959 on Linux Ubuntu 20

Is this an auk error or a problem with the best practice doc working example?

Many thanks Paul

What this error means is that there's no group_identifier column in either the EBD or SED file. Try importing the data with read_ebd(f_ebd, unique = FALSE) and see if the group_identifier field is there.
