Description

Converts from an existing GRASS 7 environment an arbitrary vector dataset into a sf object

Usage

gvec2sf(x, obj_name, gisdbase, location, gisdbase_exist = TRUE)

Arguments

x	sf object corresponding to the settings of the corresponding GRASS container
obj_name	name of GRASS layer
gisdbase	GRASS gisDbase folder
location	GRASS location name containing obj_name)
gisdbase_exist	logical switch if the GRASS gisdbase folder exist default is TRUE
