\title{Print Matrices, Old-style}
\usage{
prmatrix(x, rowlab =, collab =,
         quote = TRUE, right = FALSE, na.print = NULL, \dots)
}
\arguments{
  \item{x}{numeric or character matrix.}
  \item{rowlab, collab}{(optional) character vectors giving row or column
    names respectively.  By default, these are taken from
    \code{\link{dimnames}(x)}.}
  \item{quote}{logical; if \code{TRUE} and \code{x} is of mode
    \code{"character"}, \emph{quotes} (\samp{"}) are used.} %"
  \item{right}{ if \code{TRUE} and \code{x} is of mode
    \code{"character"}, the output columns are \emph{right}-justified.}
  \item{na.print}{how \code{NA}s are printed.  If this is non-null, its
    value is used to represent \code{NA}.}
  \item{\dots}{arguments for \code{print} methods.}
}
\description{
  An earlier method for printing matrices, provided for S compatibility.
}
\details{

  is very similar to the S function of the same name.
}
\value{
  Invisibly returns its argument, \code{x}.
