R implementation of the 'Octave' package 'signal', containing a variety of signal processing tools, such as signal generation and measurement, correlation and convolution, filtering, filter design, filter analysis and conversion, power spectrum analysis, system identification, decimation and sample rate change, and windowing.
The package 'gsignal' is an implementation in R of the 'Octave' package 'signal'. It provides signal processing algorithms for use with R, include the creation of waveforms, FIR and IIR filter design, spectral analysis, Fourier and other transforms, window functions, and resampling and rate changing.
The 'Octave' package 'signal' release 1.4.1 (2019-02-08) was used to port the functions to R. Note that compatibility of function parameters and return values was not explicitly pursued.
