LCF (version 1.7.0)

LC_fit: 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

# NOT RUN {
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)
# }
