Hi Ben,

Thanks for your advice.

I suppose you meant those documentation on following URL

Contributed Documentation
http://cran.r-project.org/other-docs.html


The difficulty for a beginner learning R is to find the right document.  There 
are many documents on Internet.  It'll take lengthy time going through all of 
them to find a right document to follow.  It is the same in learning other new 
subjects.

Other advice noted and thanks

B.R.
