Calculates the lorentz curves of each investigated spectrum.
Martina Haeckl, 2021: Initial version. Tobias Schmidt, 2024: Minor updates to pass CRAN checks
Arguments
- deconv_result
A list as returned by
generate_lorentz_curves()
or MetaboDecon1D.- number_of_files
Number of spectra to analyze
Value
If deconv_result
holds the result of a single deconvolution, a matrix
containing the generated Lorentz curves is returned, where each row depicts
one Lorentz curve. If deconv_result
is a list of deconvoluted spectra, a
list of such matrices is returned.
Examples
## -~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-
## Deconvolute the spectra in folder "bruker/sim_subset" into a list of
## Lorentz Curves (specified via the parameters A, lambda and x_0).

## -~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-
## Calculate the corresponding y values at each ppm value for each Lorentz
## Curve. I.e. you get a matrix of dimension n x m for each deconvolution,
## where n is the number of Lorentz Curves and m is the number of ppm values.
