merge2object_spct

Merge into object_spct

Description

Merge a filter_spct with a reflector_spct returning an object_spct object, even if wavelength values are mismatched.

Usage

merge2object_spct(
  x,
  y,
  by = "w.length",
  ...,
  w.length.out = x[["w.length"]],
  Tfr.type.out = "total"
)

Arguments

`x, y`	a filter_spct object and a reflector_spct object.
`by`	a vector of shared column names in `x` and `y` to merge on; `by` defaults to `w.length`.
`...`	other arguments passed to `dplyr::inner_join()`
`w.length.out`	numeric vector of wavelengths to be used for the returned object (nm).
`Tfr.type.out`	character string indicating whether transmittance values in the returned object should be expressed as "total" or "internal". This applies only to the case when an object_spct is returned.

Value

An object_spct is returned as the result of merging a filter_spct and a reflector_spct object.

Note

If a numeric vector is supplied as argument for w.length.out, the two spectra are interpolated to the new wavelength values before merging. The default argument for w.length.out is x[[w.length]].
