spec_filter {tidyspec} | R Documentation |
Filter spectral data by wavenumber range
Description
This function filters the spectral dataset based on a specified wavenumber ('wn') range. It requires the wavenumber column to be previously set using [set_spec_wn()]. If 'wn_min' and/or 'wn_max' are provided, the data will be filtered accordingly. If neither is provided, the original dataset is returned unchanged.
Usage
spec_filter(.data, wn_min = NULL, wn_max = NULL)
Arguments
.data |
A data frame containing spectral data. |
wn_min |
Optional numeric value. Minimum wavenumber value to keep. |
wn_max |
Optional numeric value. Maximum wavenumber value to keep. |
Value
A filtered data frame based on the wavenumber column.
Examples
set_spec_wn("Wavenumber")
spec_filter(CoHAspec, wn_min = 500, wn_max = 1800)
