This function standardizes the numeric spectral data in each column to have a mean of 0 and a standard deviation of 1 (unit variance), while preserving the wavelength column.
Usage
spec_norm_var(.data, wn_col = NULL)
Arguments
- .data
A `data.frame` or `tibble` containing spectral data.
- wn_col
A character string specifying the column name for the wavelength data. Default is `"Wn"`.
Value
A `tibble` with the standardized spectral data, containing the wavelength column and the standardized numeric columns.
