\alias{conventional2RFspDataFrame}
\title{Coercion to class 'RFsp' objects}
\description{
Generate an object of class \code{\link[=RFsp-class]{RFsp}} from conventional objects.
}
\usage{
conventional2RFspDataFrame(data, coords=NULL, gridTopology=NULL, n=1,
vdim=1, T=NULL, vdim_close_together)
}
\arguments{
\item{data}{array; of dimension \code{c(vdim, space-time-dim, n)};
contains the values of the random field}
\item{coords}{matrix of coordinates}
\item{gridTopology}{3-row-matrix or of class \code{\link[sp:GridTopology-class]{GridTopology}}; specifies
the grid vectors; either
\code{coords} or \code{gridTopology} must be \code{NULL}}
\item{n}{number of iid copies of the random field, default is 1}
\item{vdim}{number of dimensions of the values of the random field,
default is 1}
\item{T}{time component if any. The length of the temporal grid
is needed by \command{as.array} if the spatial locations are randomly
scattered.
}
\item{vdim_close_together}{
logical. Currently, only \code{vdim_close_together=FALSE}
is coded. In this case the dimensions of the data follow the order
\dQuote{locations, multivariate, repeated}.
Otherwise \dQuote{multivariate, locations, repeated}.
}
}
