HilbertVis (version 1.30.0)

showHilbertImage: display a hilbert

Description

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.

Usage

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

Arguments

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.

Value

A lattice or EBImage graphics object. For all modes except ``EBImage-batch'' it is marked ``invisible''.
