extractFDAWavelets {mlr} | R Documentation |
Description
The function extracts discrete wavelet transform coefficients from the raw
functional data.
See wavelets::dwt for more information.
Usage
extractFDAWavelets(filter = "la8", boundary = "periodic")
Arguments
|
(character(1) )
Specifies which filter should be used.
Must be one of d |la |bl |c followed by an even
number for the level of the filter.
The level of the filter needs to be smaller or equal then the time-series length.
For more information and acceptable filters see help(wt.filter) .
Defaults to la8 .

“periodic” assumes circular time series,
for “reflection” the series is extended to twice its length.
Default is “periodic”.
