Error in `.rowNamesDF<-`(x, value = value)

Hi all
With a colleague, we recently encountered the following error when trying to load the trap (transect) file into secr :
Error in `.rowNamesDF<-`(x, value = value) :
duplicate 'row.names' are not allowed
It took us a while to figure out the TransectIDs were numeric, and that transect "10" was considered a duplicate of transect "1"...
The bottom line is that secr expects alphanumeric trap IDs.
Apologies if this is stating the obvious but I couldn't find anything explicit about this in the documentation (I may have missed it), so I thought I'd post here... I might avoid some headache to someone...

I don't think 'secr' expects non-numeric transect ID, or that 1 = 10, so something else is wrong. Maybe you could post a minimal example of the file, with the code you used to read it.
