Hi RogerHere is the file imported from the original .csv file. I suspect it may have originated as a .qvd file converted to .csv.
The geometry string column contains [] separated geographical coordinates of somewhat varying formatting (the string versions of first and last ring coordinates are not always equal, I think), in an undocumented format.
There is certainly no existing function to read this. Use string handling to convert to a format that can be read, most likely Well-Known Text. This will involve quite advanced regular expression handling. The sample data look like POLYGON objects (an exterior ring and interior rings), but they might also be MULTIPOLYGON objects. From there, sf::st_as_sfc(). WKT does not group coordinates as ((1,1),(2,2)), rather as (1 1, 2 2).
It would still be very useful to know the provenance of the file in some detail. It is not likely that anyone will help you write the regular expression code to handle this data unless it can be generalised to a common use case (you suggested QVD (QlikView)).
