conform_spec: Conform spectra to a standard wavenumber series

Description

Spectra can be conformed to a standard suite of wavenumbers to be compared with a reference library or to be merged to other spectra.

Usage

conform_spec(x, ...)
# S3 method for default
conform_spec(x, ...)
# S3 method for OpenSpecy
conform_spec(x, range = NULL, res = 5, allow_na = F, type = "interp", ...)

Value

adj_intens() returns a data frame containing two columns named "wavenumber" and "intensity"

Arguments

x: a list object of class OpenSpecy.
range: a vector of new wavenumber values, can be just supplied as a min and max value.
res: spectral resolution adjusted to or NULL if the raw range should be used.
allow_na: logical; should NA values in places beyond the wavenumbers of the dataset be allowed?
type: the type of wavenumber adjustment to make. "interp" results in linear interpolation while "roll" conducts a nearest rolling join of the wavenumbers. "mean_up" only works when Spectra are being aggregated, we take the mean of the intensities within the wavenumber specified. This can maintain smaller peaks and make spectra more similar to it's less resolved relatives. mean_up option is still experimental.
...: further arguments passed to approx()
