\details{
  A hyperframe is like a data frame, except that its entries
  can be objects of any kind.

  The generic function \code{as.hyperframe} converts any suitable kind
  of data into a hyperframe.

  There are methods for the classes
  \code{data.frame} and \code{listof}, and a default method,
  all of which convert data that is like a hyperframe into
  a hyperframe object. (The method for the class \code{listof}
  converts a list of objects, of
  arbitrary type, into a hyperframe with one column.)
  These methods do not discard any information.

  There are also methods for other classes
  (see \code{\link{as.hyperframe.ppx}}) which extract
  the coordinates from a spatial dataset. These methods
  do discard some information.
}
\value{
  An object of class \code{"hyperframe"} created by
  \code{\link{hyperframe}}.
