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.
