fasterRaster contains a set of “private” functions
that users can access using fasterRaster:::functionName
.
These functions are useful for power users and developers. Not all
hidden functions are listed here. Often, a method will have a hidden
function of the same name that starts with a period (e.g.,
.plot()
). This “period” function is intended to be supplied
the sources()
name of a GRaster
or GVector
from other
functions so that the calling function does not need to spend the time
creating the GRaster
or GVector
pointer before
calling the function. “Period” functions will, though, often work on
GRaster
s or GVector
s, though some
error-checking and region re-definition is not conducted.
.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.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.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?.layerIndex()
: Gets the index of GRaster
layers from a numeric, integer, character, or logical vector.makeGRaster()
and .makeGVector()
: Make
GRaster
s or GVector
s 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.frame
s, data.table
s, and/or empty
strings..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.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)~ FINIS ~
