x[[i]] <- value 
x$i 
x$i <- value 

REQUIRED ARGUMENTS:

x
an object inheriting from class "crystal.matrix".
i
a vector of crystal names, positive integers or logical vector. For [[, i must be an integer or a crystal name.

OPTIONAL ARGUMENTS:

value
replacement value for the relevant piece of the crystal.matrix.

DETAILS:

See the chapter "More on Wavelet Analysis" of the S+WAVELETS User's Manual for details and examples of subscripting and assignment.

VALUE:
