#' Converts an R model object into a table.

#' It parses a fitted R model's structure and extracts the components
#' needed to create a dplyr formula for prediction. The function also
#' creates a data frame using a specific format so that other
#' functions in the future can also pass parsed tables to a given
#' formula creating function.
#'
#' @param model An R model object.
