A convenient wrapper around levelplot to display a hilbert image matrix as it is returned by hilbertImage. Alternatively to levelplot, EBImage is available as well.

showHilbertImage( mat, 
   palettePos = colorRampPalette(c("white", "red"))(300), 
   paletteNeg = colorRampPalette(c("white", "blue"))(300), 
   maxPaletteValue = max(abs(mat)), 
   mode = c("lattice", "EBImage", "EBImage-batch") )

`mat`	The matrix to be displayed. In principle this can be any matrix, but typically, it is one returned by `hilbertImage`.
`palettePos`	The colour palette to be used for the positive entries in `mat` (including 0).
`paletteNeg`	The colour palette to be used for the negative entries in `mat`.
`maxPaletteValue`	The absolute value to which the right end of the palettes should correspond. (The left ends correspond to 0.)
`mode`	For mode "lattice", the function `levelplot` from the `lattice` package is used. An (invisible) lattice object is returned that can be displayed with `show`. In interactive mode, the image is displayed automatically. For mode "EBImage" the image is displayed with the `EBImage` package, and for "EBImage-batch", the same image is produced and not displayed but rather returned as a value suitable to be passed to EBImage's `display` function.
