Fast continuous wavelet transform

Functions for performing fast continuous wavelet transforms.

fcwt()

Fast continuous wavelet transform

fcwt_batch()

Fast continuous wavelet transform - Batch processing

Plotting

Optional ggplot2 plotting methods (only work if ggplot is installed).

plot(<fcwtr_scalogram>)

Scalogram plotting

Data frame conversion

as.data.frame(<fcwtr_scalogram>)

Coerce the scalogram matrix to a data frame

Sample data

Sample signal data mainly used to generate examples. The signals consist of simple superpositions of sinusoidal patterns.

ts_sin_440

Pure sine wave

ts_sin_sin

A sinusoidal wave with varying frequency

ts_sin_superpos

Superimposed sine waves of different frequencies and different amplitudes
