hanaml.IWPT.Rd
hanaml.IWPT is the R wrapper for PAL inverse discrete wavelet packet transform.
hanaml.IWPT(wpt = NULL, filter = NULL, boundary = NULL)
WPT
A WPT
object that contains the wavelet packet coefficients and coefficient order
for applying the inverse transformation.
The WPT
object is assumed to contain other related
information for inverse transformation, like wavelet filter and boundary
extension method.
character, optional
Specifies the wavelet filter used for inverse wavelet packet transform.
It is assumed to be the same as the filter used for wavelet packet transform.
Valid options include:
Daubechies family: "db1" ~ "db20".
Biorthognal family: "bior1.1", "bior1.3", "bior1.5", "bior2.2", "bior2.4", "bior2.6", "bior2.8", "bior3.1", "bior3.3", "bior3.5", "bior3.7", "bior3.9", "bior4.4", "bior5.5", "bior6.8".
Reverse Biorthogal family: "rbio1.1", "rbio1.3", "rbio1.5", "rbio2.2", "rbio2.4", "rbio2.6", "rbio2.8", "rbio3.1", "rbio3.3", "rbio3.5", "rbio3.7", "rbio3.9", "rbio4.4", "rbio5.5", "rbio6.8"
Coifman family: "coif1" ~ "coif5".
Symmetric family: "sym2" ~ "sym20".
Defaults to wpt$filter
.
character, optional
Specifies the padding method for boundary values.
Valid options include:
"zero": Zero padding
"symmetric": Symmetric padding
"periodic": Periodic padding
"reflect": Reflect padding
"smooth": Smooth padding
"constant": Constant padding
Defaults to wpt$boundary
.
A DataFrame containing the reconstructed time-series data from the given wavelet packet coefficients.
Perform inverse discrete wavelet packet transform given an WPT
object that
contains discrete wavelet coefficients, as well as other related information for
applying the inverse transformation.
