How to add library to R

Download additional library: klaR_0.6-3.tar.gz, the source for this library CRAN klaR
Install library in your local R_LIBS directory (/Users/users/<your_name>/Rlib):
R CMD INSTALL -l /Users/users/<your_name>/Rlib klaR_0.6-3.tar.gz

How to start using mysql from R

You do not need to do this any more, RMySQL is installed in default Rlib path, /Users/users/belikov/local/lib64/R/library You can check your R_LIBS path in R

R> .libPaths()

[1] "/Users/users/belikov/local/lib64/R/library"

Please, note that you should remove old version of RMySQL from your R libraries

Download additional libraries you need for R: Rlib.tgz
Unpack in your home directory, for example, /Users/users/<your_name> with command tar -xzvf Rlib.tgz (directory Rlib will be created)
include the path to these libraries in the search path of R: setenv R_LIBS /usr/lib/R/library:/Users/users/<your_name>/Rlib
check in R that you can load this library with command library(RMySQL)
