createSpectra: Create a Spectra object
In ASICS: Automatic Statistical Identification in Complex Spectra

Description Usage Arguments Value See Also Examples

Create a new spectra object used for quantification.

1	createSpectra(spectra, norm.method = NULL, norm.params = NULL)

`spectra`	Data frame with spectra in columns and chemical shifts in rows. Colnames of this data frame correspond to pure metabolite names and rownames to chemical shift grid (in ppm).
`norm.method`	Character specifying the normalisation method to use on spectra ONLY if the `importSpectra` function was not used.
`norm.params`	List containing normalisation parameteres (see `normaliseSpectra` for details) ONLY if the `importSpectra` function was not used.
