x:

any numeric S-PLUS object.

crystal.name:

crystal name.

shift:

location at given level and block, see details below.

wavelet:

wavelet name: "d2", "d4", "c6", "s8", etc. See wavelet for a list of all available wavelet names.

boundary:

a character string giving the boundary rules, e.g. "periodic". See dwt for a list of all available boundary rules.

pdeg:

for boundary="polynomial" and "infinite" only: degree of polynomial used for boundary extension.

pfrac:

for boundary="infinite" only: fraction of data used to fit a polynomial of degree pdeg.

precondition:

logical flag: for boundary="interval" only. See dwt for details.

dual:

logical flag indicating if dual filter is used for analysis instead of synthesis.

analysis.filter:

for user defined filter only. See dwt for details.

synthesis.filter:

for user defined filter only. See dwt for details.
