Michael,

you need to install the R system first and then the add-on package vcd.
If you look at 
  http://www.R-project.org/
there are some manuals and the FAQ which will tell you how to obtain 
and install R on your operating system. Having done that you can 
install the package "vcd" which is also covered in the documentation I 
mentioned above.
Both R itself and the vcd package can be downloaded from
  http://CRAN.R-project.org/

HTH,
Z
