In aphalo/photobiologyFilters: Spectral Transmittance and Spectral Reflectance Data

#' @title Refractive-index spectra for materials
#'
#' @description A collection of refractive-index spectra for some materials.
#'
#' @details The \code{"generic_mspct"} object contains \code{"generic_spct"}
#'   objects with refractive index data.
#'
#'   The variables in each member spectrum are as follows: \itemize{ \item
#'   w.length (nm) \item n \item k }
#'
#' @note Data labeled "for unrestricted use" originate from the Filmmetrics
#'    Refractive Index Database at
#'    \url{https://www.filmetrics.com/refractive-index-database} where
#'    primary sources are provided. The names in \code{refractive_index.mspct}
#'    are the same as in the downloaded files, except for the `.txt` tag.
#'
#' @docType data
#' @keywords datasets
#' @format A \code{"generic_mspct"} object containing multiple
#'   \code{"generic_spct"} objects.
