LC_fit: Linear combination fitting function

In LCF: Linear Combination Fitting

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)
