R help - Sep 2011 - Package dependency

Greetings R community,
 
I am making my first package and have run into the need to use other packages. 
I  pass all the checks in the command prompt running Rcmd check package.name. 
In the Description file I have included:
 
Depends: R (>= 2.13), plotrix
Repository: CRAN
 
Now I create the zip file for windows 7.  I delete my plotrix package from my
library to create a setup where others might encounter when installing my
package (perhaps they don't have the package dependency plotrix installed). 
I now install the zip file in my R library and try to load it in R generating
the following error:
 
> library(genTools)
Loading required package: plotrix
Error: package ‘plotrix’ could not be loaded
In addition: Warning message:
In library(pkg, character.only = TRUE, logical.return = TRUE, lib.loc = lib.loc)
:
  there is no package called ‘plotrix’
 
Now the question:  How do I get my package to automatically download
dependencies from CRAN as other CRAN packages do when I install them to my
library for the first time?

if you have declared stuff as above and CRAN is among the current 
repositories, install.packages() will install the dependencies for you.
