Interpolate Spectral Data to Include Both Grids (Right Join Style)

Source: R/spec_interpolation.R
spec_interpolate_right.Rd

This function interpolates reference data to match the wavenumber grid of the main dataset. Works like a right join - keeps all wavenumbers from .data and interpolates reference data to match those wavenumbers.

Usage

spec_interpolate_right(
  .data,
  reference,
  wn_col = NULL,
  method = "pchip",
  extrapolate = FALSE,
  suffix = c(".x", ".y"),
  ...
)

Arguments

.data

A `data.frame` or `tibble` containing the main spectral data.

reference

A `data.frame` or `tibble` containing spectral data to be interpolated.

wn_col

A character string specifying the column name for the wavenumber data.

method

A character string specifying the interpolation method.

extrapolate

Logical. Should values be extrapolated outside the original range?

suffix

Character vector of length 2 specifying suffixes for overlapping column names.

...

Additional arguments passed to the interpolation method.

Value

A `tibble` combining .data with interpolated reference data.
