\details{
  The function \code{iplot} generates a plot of the spatial dataset \code{x}
  and allows interactive control over the appearance of the plot
  using a point-and-click interface.

  The function \code{iplot} is generic, with methods for
  for point patterns (\code{\link{iplot.ppp}}),
  layered objects (\code{\link{iplot.layered}})
  and a default method. The default method will handle objects of
  class \code{"psp"}, \code{"im"} and \code{"owin"}
  at least.

  A new popup window is launched. The spatial dataset
  \code{x} is displayed in the middle of the window using the
  appropriate \code{plot} method.

  The left side of the window contains
  buttons and sliders allowing the user to change the plot parameters.

  The right side of the window contains navigation controls for
  zooming (changing magnification), panning (shifting the
  field of view relative to the data), redrawing and exiting.

  If the user clicks in the area where the point pattern is displayed,
  the field of view will be re-centred at the point that was clicked.
