ir_new_ir {ir}

R Documentation

Creates an object of class `ir`

Description

ir_new_ir is the constructor function for objects of class ir. An object of class ir is a tibble::tbl_df() with a sample in each row and a list column containing spectra for each sample.

Usage

ir_new_ir(spectra, metadata = tibble::tibble())

Arguments

`spectra`	A named list in which each element contains spectral data for one measurement. Each list element must be a `data.frame` with two columns and a row for each wavenumber value in the spectra data. The first column must contain unique wavenumber values and the second column intensity values of the measured spectrum of the sample.
`metadata`	An optional `data.frame` with additional columns containing metadata for the spectra in `spectra`. Optionally, an empty `data.frame` can be defined if no metadata are available.

Value

An object of class ir with the following columns:

spectra: A list column identical to spectra.
...: Additional columns contained in metadata.

Examples

ir_new_ir(
  spectra = ir_sample_data$spectra,
  metadata = ir_sample_data %>% dplyr::select(-spectra)
)
