#' General plot function for RLum S4 class objects
#'
#' Function calls object specific plot functions for RLum S4 class objects.
#'
#' The function provides a generalised access point for plotting specific
#' [RLum-class] objects.\cr
#' Depending on the input object, the
#' corresponding plot function will be selected.  Allowed arguments can be
#' found in the documentations of each plot function.

#'
#' @param object [RLum-class] (**required**):
#' S4 object of class `RLum`. Optional a [list] containing objects of
#' class [RLum-class] can be provided. In this case the function tries to plot
#' every object in this list according to its `RLum` class. Non-RLum objects are
#' removed.
#'
#' @param ... further arguments and graphical parameters that will be passed
#' to the specific plot functions. The only argument that is supported directly is `main`
#' (setting the plot title). In contrast to the normal behaviour `main` can be here provided as
#' [list] and the arguments in the list will dispatched to the plots if the `object`
#' is of type `list` as well.
#'
#' @return Returns a plot.
#'
#' @note The provided plot output depends on the input object.
