The structure and function of the error column

[birderboone]

This column/attribute has largely been in a placeholder that we wanted to make sure existed, but wasnt sure what it would look like.

So lets start the discussion, what does an error column need to do? What structure should it look like? What should be required for it?

Is this a post processing column where you create the error using various other packages and its simply a column that stores the error. Or is it a column that you create with as_sftrack and contains all the error variables you can use later (i.e hdop, vdop, etc).

Closing this issue now that sftrack is developed and on CRAN.
