This function is generic (see Methods); method functions can be written to handle specific classes of data. Classes which already have methods for this function include:
atrous, cp.crystal, decompose, dwt, molecule, mra,, nd.dwt, rob.dwt, wp.crystal, wpt.2d.
crystal.names(x, J, Jrow=J, Jcol=Jrow, depth.first=F, style="pretty", case="lower") is.2d.name(x) is.pretty.names(x) icrystal.names(x, J, Jrow=J, Jcol=Jrow, depth.first=F)
is.2d.name returns TRUE if x is a vector of 2D crystal.names, and FALSE otherwise.
is.pretty.names returns TRUE if x is a vector of "pretty" crystal names, and FALSE otherwise.
icrystal.names returns the internal crystal names. This function is not intended for high-level use.
When x="cp", "block.dct", the crystal names are of the form: cj.b (if case="lower") or Cj.b (if case="upper"), where j is the resolution level, b is the block number and c (or C) stands for "cosine packet". Argument style is ignored.
When x="dwt" and style="pretty", the crystal names are of the form: sj, dj (if case="lower") or Sj, Dj (if case="upper"), where j is the resolution level, s (or S) stands for "smooth" and d (or D) stands for "detail".
When x="wp", "subband" and style="pretty", the crystal names are of the form: wj.b (if case="lower") or Wj.b (if case="upper"), where j is the resolution level, b is the block number (under "sequency" order) and w (or W) stands for "wavelet packet".
When x="mra" and style="pretty", the crystal names are of the form: Sj, where j is the resolution level. Argument case is ignored.
When style != "pretty", the crystal names will be strings of Ls and Hs, where L is for "low-pass" and H is for "high-pass". The length of the string equals to the resolution level and the combination of the Ls and Hs determines the block number.
When x="dwt.2d", "cp.quad", "wp.quad", "subband.2d", "block.dct.2d", 2D crystal names are created and of the form 1D.name-1D.name.
x.dwt <- dwt(rnorm(64)) crystal.names(x.dwt) # extract crystal names crystal.names(x.dwt, "pretty") # extract crystal names, in "pretty" style crystal.names("wp", 3) # create crystal names for wp table crystal.names("block.dct.2d", 2) # create crystal names for 2D block.dct
