R help - Jun 2007 - viewing source code

Hi,

could somebody give me a quick hint how to view the
source code of a function if sole entering of the
function name does not work?

In particular, I am trying to look at "cd_plot" from
the vcd package.

Many thanks in advance,
  Werner

Strategy 1: Typing "cd_plot" tells you that it is a generic function
  and "methods(cd_plot)" shows you which methods exist (default and
  formula) which are both non-visible. You can still directly access
  them via "vcd:::cd_plot" (which is the main work horse).

Strategy 2 (preferred, especially if you want to take a closer look):
  Obtain the source package from CRAN. Unpack the tar.gz file and
  look into the vcd/R folder where you will find cd_plot.R containing
  the sources of both methods.
