For developers: Hidden fasterRaster functions

General

• .backdoor(): Calls [faster()] and sets GRASS folder to “C:/Program Files/GRASS GIS X.Y”, plus other options useful for development.
• .fileExt(): Get file extension
• .ls(): Lists the sources of all objects in the active GRASS “project/location”
• .message(): Display a warning or message if the given warning has not been displayed since fasterRaster was attached or if a given number of hours has passed
• .quiet(): Returns “quiet” if faster("debug") is TRUE
• .workDir(): Working directory of a GLocation object

Rasters and vectors

• .copyGSpatial(): Make a copy of the GRASS file pointed to by a GRaster or GVector
• .exists(): Does the GRASS file of a GRaster or GVector exist?
• .ext(): Extent from the sources() name of a GRaster or GVector
• .makeSourceNames(): Makes one or more statistically unique strings that can be used as file names to represent rasters or vectors in GRASS
• .plot(): Plot using the sources() name of a GRaster or GVector
• .projection(): Value of the @projection slot in a GRaster or GVector
• .rastInfo() and .vectInfo(): Metadata for a GRASS raster or vector
• .rename(): Rename a GRASS raster or vector
• .rm(): Delete rasters or vectors in GRASS

Vectors

• .aggDisaggVect(): Aggregate or disaggregate a vector using its sources() name.
• .geomtype(): Geometry type (“point”, “line”, or “area”) from the sources() name of a GVector
• .validVector(): Test if a GVector is valid.
• .vAsDataTable(): Convert the attribute table linked to a vector in GRASS to a data.table. This table is distinct from the attribute table attached to a GVector
• .vAttachDatabase(): Add a database table to the GRASS representation of a GVector
• .vCats(): Get a data.table with a single column named cat, which corresponds to the GRASS attribute table’s cat column
• .vDetachDatabase(): Detach the GRASS database from a GRASS vector
• .vHasDatabase(): Tests if GRASS vector has a database
• .vIncrementCats(): Increment category values of a GVector
• .vNames(): “GRASS” vector attribute table column names
• .vRecat(): Change GRASS category indices of a GRASS vector
• .vValidCats(): Are category values of a vector valid?

Rasters

• .layerIndex(): Gets the index of GRaster layers from a numeric, integer, character, or logical vector
• .makeGRaster() and .makeGVector(): Make GRasters or GVectors from a vector of sources, which are pointers to files in GRASS
• .minVal() and .maxVal(): Values in the @minVal and @maxVal slots in a GRaster
• .nlevels(): Number of levels in a SpatVector, data.frame, data.table, empty string, or a list of data.frames, data.tables, and/or empty strings.

GRASS “Projects/locations” and “mapsets”

• .locationCreate() Make a connection to GRASS (i.e., start GRASS from within R) and create a location
• .locationDelete() Deletes all files associated with a GRASS “location” and mapset
• .locationFind(): Find a specific GRASS “location” that already exists
• .locationRestore() Reconnect GRASS to a previously-created GRASS “location”
• .locations(): List of all available “locations”
• .g.proj(): Runs GRASS g.proj module to display projection of current “project”
• .g.region(): Runs GRASS g.region module to display region of current “project”
• .mapset(): GRASS “mapset” of an object or the active session

GRASS “regions”

• .region(): Change or report the active region’s extent and resolution
• .regionDim()]: Change or report the active region’s resolution (also dim() and related functions, with no arguments)
• .regionExt(): Change or report the active region’s extent (also ext() and related functions, with no arguments)
• .regionRes(): Change or report the active region’s dimensions (also res() and related functions, with no arguments)
