vAsDataTable: Convert a GRASS vector's attribute table to a data.table

In adamlilith/fasterRaster: Faster Raster and Spatial Vector Processing Using 'GRASS GIS'

Convert a GRASS vector's attribute table to a data.table

Description

GRASS vectors can be linked to an attribute table, which can be exported from GRASS to R using this function. This function is mostly of use to developers.

Values in the cat column are not necessarily unique–if a value appears more than once, the set of features they index are (in other software) called "multipart" features. The table can have more columns with metadata for each feature.

This function is typically used by developers.

Usage

.vAsDataTable(x)

Arguments

x	A GVector or the name of a vector in GRASS.

Value

A data.table or NULL if the vector is not attached to a database.
