     power.stretch=0.5, x.srt=90, y.srt=0,
     name.style="pretty", ...)

x:

a 2-D packet cost table object inheriting from class pcosts.2d.

level:

an integer indicating the level to be plotted.

plot:

logical flag: if TRUE, the image is plotted.

grid:

if TRUE, a grid is added between the coefficient blocks (crystals). See pgrid.plot for details.

grid.lty:

integer giving the line type for the grid of crystals. See the lty argument for par.

axes:

if TRUE, axes are added with labels for the coefficient blocks (crystals).

power.stretch:

a numeric value giving the power of the transform applied to the image before it is plotted. If power.stretch=0, then image is transformed with log(abs(x)+1). Otherwise, the image is transformed with abs(x)^power.stretch.

x.srt:

string rotation in degrees for labels in x.axis, same as srt in par, in effect when axes=TRUE.

y.srt:

string rotation in degrees for labels in y.axis, same as srt in par, in effect when axes=TRUE.

name.style:

crystal name styles: one of the character strings "pretty" or "filter". Only for 2-D DWT and 2-D wavelet packet transforms. See crystal.names for details. The default is wavelet.options()$name.style.

...:

additional arguments can be passed to image and to mtext (if axes=TRUE).
