LC_fit {LCF}

Linear combination fitting function

Description

This function performs the LC fitting of the input sample/samples. It outputs the fitting results with the R-Factors as fitting statistics.

Usage

LC_fit(sample, standards, LC.vals, float = NULL, E.zero = NULL,
  ex.smaller = NULL)

Arguments

sample

The sample spectrum

standards

The standards spectra

LC.vals

Values for ranges of linear combination fitting, with respect to the edge-step

float

Set float parameters, defaults to NULL

E.zero

Set E0, defaults to NULL

ex.smaller

Set value to exclude small portions (as portion of 1), defaults to NULL

Examples

data(stdmix)
corr.spec.standards  <- initial_load(specdat[1:4], 
  corr.norm = c(-36, -15, 37, 58))
corr.spec.samples    <- initial_load(specdat[5:8], 
  corr.norm = c(-36, -15, 37, 58))
fit.standards <- std_df(sample = corr.spec.samples[[1]], 
  all.standards = corr.spec.standards)
fit.result <- LC_fit(sample = corr.spec.samples[[1]], 
  standards = fit.standards, LC.vals = c(-14, 46))
print(fit.result)
