Use the official R installer to install R and then the usual  
install.packages(...) to install the packages. On some systems you can  
"freeze" all this by simply packaging it all into one archive (if you  
know where all relevant files are). I would not recommend that for R  
itself because the installers have important side-effects, but you can  
safely archive packages as long as you unpack them in exactly the same  
location.
