cycles {astrochron} | R Documentation |
Make a time series with specified harmonic components and noise
cycles(freqs=NULL,phase=NULL,amp=NULL,start=0,end=499,dt=1,noisevar=0,genplot=T, verbose=T)
freqs |
Vector with frequencies to model ('linear' frequencies). |
phase |
Vector with phases for each frequency (phase in radians). Phases are subtracted. |
amp |
Vector with amplitudes for each frequency. |
start |
First time/depth/height for output. |
end |
Last time/depth/height for output. |
dt |
Sampling interval. |
noisevar |
Variance of additive Gaussian noise. |
genplot |
Generate summary plots? (T or F) |
verbose |
Verbose output? (T or F) |
modeled time series.
