[GRASS-stats] rgrass7 - SQLite and GML drivers not working for readVECT

[Veronica Andreo]

Hello all,

Are SQLite and GML drivers disabled/broken in readVECT? I only get
driver="ESRI Shapefile" to work, but in some cases with a lot of warnings.

Here an example with NC location:
grass73svn grassdata/nc_spm_08_grass7/PERMANENT/ --text
...
GRASS 7.3.svn (nc_spm_08_grass7):~ > R
...
>library(rgrass7)
...
> bla <- readVECT("firestations", driver="SQLite")
Error: driver %in% candDrivers is not TRUE

> bla <- readVECT("firestations", driver="GML")
Error: driver %in% candDrivers is not TRUE

> bla <- readVECT("firestations", driver="ESRI Shapefile")
Exporting 71 features...
 100%
v.out.ogr complete. 71 features (Point type) written to <firestat>
(ESRI_Shapefile format).
OGR data source with driver: ESRI Shapefile
Source: "/home/veroandreo/grassdata/nc_spm_08_grass7/PERMANENT/.tmp/
ipv6.dynamic.ziggo.nl", layer: "firestat"
with 71 features
It has 22 fields

For some vectors, I get the following warnings (loss of data apparently):

> bla2<-readVECT("census_wake2000")
Exporting 105 areas (may take some time)...

Thanks a lot in advance for any hint
