Description Usage Arguments Value Examples

PSD(f) = f^{-β}

1	power.law(N, freq.max = 1/(2 * pi), beta = 0, sd = 1)

`N`	Number of frequencies (must be even).
`freq.max`	Value of largest frequency.
`beta`	Value of power.
`sd`	Standard deviation.

Frequencies and power spectral density.

power.law(100)                # 100 samples with default options
power.law(100, freq.max = 50) # provide maximum frequency
power.law(100, sd = 2.0)      # provide standard deviation
power.law(100, beta = 0.0)    # white noise
power.law(100, beta = 1.0)    # 1/f noise
power.law(100, beta = 2.0)    # brown noise
