I'd start with the home page for R: http://www.r-project.org/
because you seem to have no idea what version is current
(3.0.1). You will find Google to be very helpful. As for
manuals, the official documentation is at


and the user contributed manuals are at

http://cran.r-project.org/other-docs.html which includes "R
and Data Mining: Examples and Case Studies" by Yanchang Zhao
(PDF, 2013-04-26, 160 pages).

the Task Views are at


There are a number of other useful web sites including


Just to get you started.

Subject: [R] Unable to install packages

Hi all. I am new to R. I have just installed R2.10.1 for my
Windows 7
computer. When I go to Packages > Install Packages on the
drop-down list, I
get the message:

"Warning: unable to access index for repository
Warning: unable to access index for repository
Error in install.packages (Null, .libPaths () [1L],
dependencies = NA, type
= type) :
   no packages were specified"

Please advise suitably.

Also suggest any good free online book/free online recognized
course to *
quickly* master R for data mining.
