Class RFgridDataFrame
Class for attributes in one-dimensional space.
## S4 method for signature 'RFgridDataFrame' RFspDataFrame2conventional(obj, data.frame=FALSE)
obj |
an |
data.frame |
logical. If |
Objects can be created by using the functions
RFgridDataFrame or
conventional2RFspDataFrame or by calls of the form
as(x, "RFgridDataFrame"), where x is of class
RFgridDataFrame.
.RFparams:list of up to 5 elements;
n is the number
of repetitions of the random field contained in the data slot
vdim gives the dimension of the values of
the random
field, equals 1 in most cases
has.variance
indicates whether information on the variance is available,
coordunits gives the names of the
units for the coordinates
varunits gives the names of the
units for the variables
data:object of class data.frame,
containing attribute data
grid:object of class GridTopology.
signature(obj =
"RFgridDataFrame"): generates nice plots
of the random field; if space-time-dim2, a two-dimensional
subspace can be selected using the argument
MARGIN; to get different slices in a third direction, the
argument MARGIN.slices can be used;
for more details see plot-method or type
method?plot("RFgridDataFrame")
signature(x = "RFgridDataFrame"):
uses the show-method for class SpatialGridDataFrame.
signature(x = "RFgridDataFrame"):
identical to show-method
signature(obj =
"RFgridDataFrame"): conversion to a list of
non-sp-package based objects; the data-slot
is converted to an array of dimension [1*(vdim>1) +
space-time-dimension + 1*(n>1)]
signature(x = "RFgridDataFrame"):
returns the coordinates
signature(x = "RFgridDataFrame"): selects
columns of data-slot; returns an
object of class RFgridDataFrame.
signature(x = "RFgridDataFrame"): replaces
columns of data-slot; returns an
object of class RFgridDataFrame.
signature(x = "RFgridDataFrame"):
converts into other formats, only implemented for target class
RFpointsDataFrame
signature(...): if arguments have identical
topology, combine their attribute values
signature(x = "RFgridDataFrame"): returns the range
signature(x = "RFgridDataFrame"): plots histogram
signature(x = "RFgridDataFrame"): converts
data-slot to matrix
signature(x = "RFgridDataFrame"): converts
data-slot to array
signature(x = "RFgridDataFrame"): converts
data-slot to vector
signature(x = "RFgridDataFrame"):
converts data-slot and coordinates to a data.frame
Methods summary and dimensions
are defined for the “parent”-class
RFsp.

RFspatialGridDataFrame,
which is for point
locations in higher dimensional spaces,
RFpointsDataFrame-class which is for one-dimensional
arbitrary locations,
