I have Revolution-R-Community-4.3.0 which comes with R version 2.12.2. I want to update to R 2.14. I like to do this keeping some of the performance enhancing libraries of Revolution-R.
If I am to put this in another way. How is it I can create my own distribution of R which has the same performance. Also that are packaged that are included in Revo. R that I can add to my installation.
You don't. REvo R's latest uses R 2.13.2.
If you want R 2.14.0, install it directly. It comes free, so there is no reason not to.
