Nothing
#
# This file defines a generic function to convert matrices. spatialwarningsGis
# will add methods to this generic function so that foreign gis formats can be
# directly used in spatialwarnings.
#

#'
#' @title Convert an object to a matrix
#'
#' @description This function is mainly for internal use by the
#' \code{\link{spatialwarnings}} package to convert objects before they are
#' processed by \code{*_sews} functions.
#'
#' @param object An object (typically, a matrix or a list of matrices)
#'
#' @param ... Additional arguments (currently ignored)
#'
#' @details
#' This generic function is here so that other packages can extend it.
#' For example, \href{https://github.com/spatial-ews/spatialwarningsGis}{spatialwarningsGis} will provide methods so that GIS objects can be handled
#' (e.g. \code{RasterLayer} from package \code{raster}).
