showHilbertImage {HilbertVis} | R Documentation |
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.
|
A lattice or EBImage graphics object. For all modes except ``EBImage-batch'' it is marked ``invisible''.
