Dear Markus,

I can't see how to get the same strings out without conditioning,


with

ogrDGRASSs <- gsub(" ", "_", trimws(sapply(strsplit(ogrDGRASS, " [(]"),
"[", 1)))


because for v.in.ogr -f and GDAL >= 2.0, GRASS < 7.3 presents for example:

GML (rw): GML
SQLite (rw): SQLite
ESRI Shapefile (rw): ESRI Shapefile
GeoJSON (rw): GeoJSON

(readOGR used the string following ":" )


The structure of the output of r.in.gdal -f and v.in.ogr -f is

 (): 

readOGR must use the string preceding "(". Anything following ":" is a
description which can change any time. Before GDAL 2.0, there was nothing
else but the short name for OGR drivers, therefore the short name was used
as description.



and >= 7.3:

GML (rw+): Geography Markup Language (GML)
SQLite (rw+): SQLite / Spatialite
ESRI Shapefile (rw+): ESRI Shapefile
GeoJSON (rw+): GeoJSON

where the string after ":" is different.


the string before the read/write flags, i.e. before "(" is identical.


If we can depend on all GRASS < 7.3 having the same short name position,

yes, I could avoid conditioning by changing the string processing to suit

= 7.3 and apply it to all previous; I chose not to modify the string

processing for < 7.3 to avoid any problems I can't readily check.

For all versions of GRASS 7 and all versions of GDAL, the short name
position has been and continues to be the first position. For v.in.ogr -f,
the short name may also appear after ":", but only if there is no long name.

Best regards,

Markus



Best wishes,

Roger

I can add the backwards_compatibility=TRUE flag to readVECT() once it is

However, using v.external instead of v.in.ogr fix this single problem
because of the way the output is different (in form).
For example, if you use v.in.ogr you will have to compare



SQLite_/_Spatialite



(GRASS) to SQLite (R) and they are not the same.

Dear Roger, MarkusM and all

Thank you very much for such quick answers and solutions! I cannot tell
which would be the best solution, but I tested the one already in r-forge
and readVECT works again with SQLite and GML :)

Thanks again to everybody!
