In EarthSystemDiagnostics/paleospec: Spectral tools for the ECUS group

Fit a power-law to the spectrum

Description

Fit a power-law to the spectrum

Usage

SlopeFit(
  spec,
  freq.start = NULL,
  freq.end = NULL,
  bDebug = TRUE,
  breaks = NULL,
  indexRemove = NULL,
  df.log = 0.05,
  i.fStart = 4
)

Arguments

spec	power spectrum as list with $freq and $spec
freq.start	vector containing the start frequencies of the fitting interval(s)
freq.end	vector containing the end frequencies of the fitting interval(s)
bDebug	(TRUE) plot diagnostics
breaks	vector of breakpoints to which the spectra is binned (optional)
indexRemove	bins that are removed (e.g. containing the annual and semiannual cycle)
df.log	resolution of the bins (if breaks are not provided)
i.fStart	index of first (lowest) frequency to be used

Value

list(slope=slope,slopesd=slopesd,spec=saveSpec,freq=binFreq,intercept=intercept)
