[R] fail in adding library in new version.

[Ivy_Li]

Hello everybody,
	Could I consult you a question?
	I always use R old version 1.9.1 . Because I can not add my library into the new version 2.0.0 by the same method as old version. 
*	I have read the webpage <http://www.stats.ox.ac.uk/pub/Rtools> 
*	Download the tools.zip 
*	Unpack tools.zip into c:\cygwin
*	Install Active Perl in c:\Perl
*	Install the mingw32 port of gcc in c:\mingwin
*	Then go to "Control Panel -> System -> Advanced -> Environment Variables -> Path -> Variable Balue" add ;c:\cygwin;c:\mingwin\bin
*	Save my library "example" into "c:\MyRpackages\" . But I am not sure what type it is, is it need suffix?" And I don't what its content, just my function script, no special format? 
*	Then I don't know where should I do this step: Type R CMD INSTALL --build example. Need I run R first?
	So There is a error after I do this step.  It said it can not find somethig. I don't which step is wrong. It costed me much time.
	
	Could anyone help me to settle this problems?
	Thanks very much!
