\title{Heat map from equal length x,y,z vectors}
\description{
  Provides an interface to use \code{image} by providing three equal length vectors for x, y and z coordinates. 
}
\usage{
image_xyz( x , y , z , ... )
}
%- maybe also 'usage' for other objects documented here. 
\arguments{
  \item{x}{vector of x values}
  \item{y}{vector of y values}
  \item{z}{vector of z values}
  \item{...}{other parameters to pass to \code{image}}
}
\details{
  This function merely constructs a matrix suitable for \code{image}, using x, y and z coordinates.
