\title{Class \code{RFgridDataFrame} }
\description{ Class for attributes in one-dimensional space.}
\usage{
\S4method{RFspDataFrame2conventional}{RFgridDataFrame}(obj, data.frame=FALSE)
}
\arguments{
\item{obj}{an \code{RFgridDataFrame} object}
\item{data.frame}{logical. If \code{TRUE} a \code{data.frame} is returned.
}
}
\section{Creating Objects}{
Objects can be created by using the functions
\code{\link{RFgridDataFrame}} or
\code{\link{conventional2RFspDataFrame}} or by calls of the form
\code{as(x, "RFgridDataFrame")}, where \code{x} is of class
\command{\link[=RFgridDataFrame-class]{RFgridDataFrame}}.
%Ordered full grids are stored instead or unordered non-NA cells;
}
\section{Slots}{
\describe{
\item{\code{.RFparams}:}{list of up to 5 elements;
\itemize{ \item{n} is the number
of repetitions of the random field contained in the \code{data} slot
\item \code{vdim} gives the dimension of the values of
the random
field, equals 1 in most cases
\item \code{has.variance}
indicates whether information on the variance is available,
\item \code{coordunits} gives the names of the
units for the coordinates
\item \code{varunits} gives the names of the
units for the variables
}
}
\item{\code{data}:}{object of class \code{\link[methods:data.frame-class]{data.frame}},
containing attribute data }
\item{\code{grid}:}{object of class \code{\link[sp:GridTopology-class]{GridTopology}}.}
}
}
\section{Methods}{
\describe{
\item{plot}{\code{signature(obj =
"RFgridDataFrame")}: generates nice plots
of the random field; if \eqn{space-time-dim2}, a two-dimensional
subspace can be selected using the argument
\code{MARGIN}; to get different slices in a third direction, the
argument \code{MARGIN.slices} can be used;
for more details see \code{\link{plot-method}} or type
\code{method?plot("RFgridDataFrame")}}
\item{show}{\code{signature(x = "RFgridDataFrame")}:
uses the \command{show}-method for class \code{\link[=SpatialGridDataFrame-class]{SpatialGridDataFrame}}.}
\item{print}{\code{signature(x = "RFgridDataFrame")}:
identical to \command{show}-method}
\item{RFspDataFrame2conventional}{\code{signature(obj =
"RFgridDataFrame")}: conversion to a list of
non-\pkg{sp}-package based objects; the \code{data}-slot
is converted to an array of dimension \eqn{[1*(vdim>1) +
space-time-dimension + 1*(n>1)]}}
\item{coordinates}{\code{signature(x = "RFgridDataFrame")}:
returns the coordinates}
\item{[}{\code{signature(x = "RFgridDataFrame")}: selects
columns of \code{data}-slot; returns an
object of class \code{\link[=RFgridDataFrame-class]{RFgridDataFrame}}.}
\item{[<-}{\code{signature(x = "RFgridDataFrame")}: replaces
columns of \code{data}-slot; returns an
object of class \code{\link[=RFgridDataFrame-class]{RFgridDataFrame}}.}
\item{as}{\code{signature(x = "RFgridDataFrame")}:
converts into other formats, only implemented for target class
\code{\link[=RFpointsDataFrame-class]{RFpointsDataFrame}} }
\item{cbind}{\code{signature(...)}: if arguments have identical
topology, combine their attribute values}
\item{range}{\code{signature(x = "RFgridDataFrame")}: returns the range
}
\item{hist}{\code{signature(x = "RFgridDataFrame")}: plots histogram
}
\item{as.matrix}{\code{signature(x = "RFgridDataFrame")}: converts
\code{data}-slot to matrix}
\item{as.array}{\code{signature(x = "RFgridDataFrame")}: converts
\code{data}-slot to array}
\item{as.vector}{\code{signature(x = "RFgridDataFrame")}: converts
\code{data}-slot to vector}
\item{as.data.frame}{\code{signature(x = "RFgridDataFrame")}:
converts \code{data}-slot and coordinates to a data.frame}
}
}
\section{Details}{
Methods \command{summary} and \command{dimensions}
are defined for the \dQuote{parent}-class
\command{\link[=RFsp-class]{RFsp}}.
