Error in getAdmin(df) : Input object must have a column containing the locality search string

[Lobz]

I'm getting this error when using the checkList function, and I don't know why. This data was created using the plantR functions. What could be the problem?

> list <- checkList(occs,
+             n.vouch=3, # max number of vouchers per species (hopefully it will order from best to worst?)
+             type = "selected", # unsure what the options mean
+             rm.dup = TRUE, # remove duplicates!! (does it unify duplicates??)
+             rank.type = 5 # this controls voucher ranking I think?
+             )
