[R] decomposed.ts class and method

[Spencer Graves]

Hi, Erin:

	  I tried the example in the help file for 'decompose':

      m <- decompose(co2)
      m$figure
      plot(m)

	  Consistent with your post, I got the following:

 > class(m)
[1] "decomposed.ts"

	  Then I tried the following:

 > methods(class="decomposed.ts")
[1] plot.decomposed.ts*

    Non-visible functions are asterisked

	  Then 'getAnywhere("plot.decomposed.ts")' should produce what you 
want.  Alternatively, consider the following:

 > methods("plot")
  [1] plot.acf*           plot.data.frame*    plot.Date*
  [4] plot.decomposed.ts* plot.default        plot.dendrogram*
<snip...?>

	  Thus, 'getAnywhere' should give you the plot method in this case. 
The class definition is outlined under 'Value' in the "decompose" help 
page.  For an example, try str(m).

	  hope this helps.
