In refund.shiny: Interactive Plotting for Functional Data Analyses

#' Convert data to refund objects for use in functional data analyses
#'
#' Very experimental function, primarily used to convert matrices storing functional data
#' to data.frames with specific variable names.
#'
#' @param obj Object to be converted. Currently supports class \code{matrix}, formatted
#' so that rows contain functional observations on subjects.
#' @param ... additional arguments to be passed to methods.

#'
#' @return An object of classes \code{data.frame} and \code{refund.object}, the latter of
#' which is so far not used. Columns are \code{id} (taken from the rownames of \code{obj},
#' if they exist), \code{index} (with behavior described above), and \code{value} (taken
#' from entries in \code{obj}).
