spectrace_normalize_spectra: Normalize spectrace data

In steffenhartmeyer/spectrace: Functions for importing and processing raw Spectrace output

Normalize spectrace data

Description

This function normalizes the spectral data.

Usage

spectrace_normalize_spectra(
  lightData,
  method = c("peak", "AUC", "wavelength", "response"),
  wavelength = NULL,
  response = c("vl", "sc", "mc", "lc", "rod", "mel"),
  keepNormCoefficient = FALSE
)

Arguments

lightData	Data frame containing the (calibrated) light data. Data needs to be in wide format (see spectrace_to_wide).
method	String specifying the normalization method. If method is "peak" (default), data is normalized such that the peak (max value) is equal to 1. If method is "AUC", data is normalized such that the area under the curve is equal to 1. If method is "wavelength", data is normalized to 1 at specified wavelength.
wavelength	Numeric. Wavelength to normalize at. Must be specified if method is "wavelength".
keepNormCoefficient	Logical. Should the normalization coefficient be kept in the data? Defaults to FALSE

Value

The original data frame with the spectral data replaced by the normalized spectral data.
