R help - Feb 2006 - decomposed.ts class and method

Dear R People:

In the function "decompose", the object has the class of
"decomposed.ts".
(from package stats)

I would like to see the class definition and the method for the plotting.

However, when I use
isClass("decomposed.ts")

I get "FALSE".

When I check getMethods("plot")

there is no method for plot on decomposed.ts

Any suggestions, please?

Thanks in advance!

R Version 2.2.1 Windows

Try:

getAnywhere(plot.decomposed.ts)
getAnywhere(print.decomposed.ts) # not found; its using print.default

Also note this gives an S3 generic's methods:

methods(plot)

This is an S3 class, not an S4 class.  (Package stats does not use S4 
classes: only package stats4 in the R tarball does.)

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.
