Create a GRaster

Create a GRaster from a raster existing in the current GRASS session.

Usage

.makeGRaster(src, names = "raster", levels = "", ac = NULL, fail = TRUE)

src: Character (name of the raster in **GRASS) or a rastInfo object.
names: Character: Name of the raster.
levels: NULL (default), a data.frame, data.table, an empty string (""), or a list of data.frames, data.tables, and/or empty strings: These become the raster's levels(). If "", then no levels are defined.
ac: Vector of numeric/integer values >=1, or NULL (default): Active category column (offset by 1, so 1 really means the second column, 2 means the third, etc.). A value of NULL uses an automated procedure to figure it out.
fail: Logical: If TRUE (default), and the raster either has a 0 east-west or north-south extent, then exit the function with an error. If fail is FALSE, then display a warning and return NULL.
