### ** Examples

require(graphics)
## Don't show: 
 setClass("track",
          representation(x="numeric", y="numeric"))
 ## First, with only one object as argument:
 setMethod("plot", signature(x="track", y="missing"),
           function(x,  y, ...) plot(slot(x, "x"), slot(x, "y"), ...))
 ## Second, plot the data from the track on the y-axis against anything
 ## as the x data.
 setMethod("plot", signature(y = "track"),
           function(x, y, ...) plot(x, slot(y, "y"), ...))
 setMethod("plot", "track",
           function(x, y, ...) plot(slot(x, "y"), y,  ...))
## End Don't show
## Assuming the methods for plot
## are set up as in the example of help(setMethod),
## print (without definitions) the methods that involve class "track":
showMethods("plot", classes = "track")
## Not run: 
##D # Function "plot":
##D # x = ANY, y = track
##D # x = track, y = missing
##D # x = track, y = ANY
##D 
##D require("Matrix")# a CRAN package with much S4 functionality
##D showMethods("%*%")# many!
##D     methods(class = "Matrix")# nothing
##D showMethods(class = "Matrix")# everything
## End(Not run)
