How to Install R for Mac and Use a Few Basic Functions

Find the R package here: http://cran.r-project.org/ Download the latest version Then click Tools and download

This is for SnowLeopard version of MaxOSX

gfortran-4.2.3.pkg (OS X 10.5+, signed, 64-bit driver) and tcltk-8.5.5-x11.pkg (OS X 10.5+, signed) (Make sure they are the latest versions by clicking on the homepage link http://cran.r-project.org/) Note: the use of X11 (including tcltk) requires XQuartz to be installed since it is no longer part of OS X. Always re-install XQuartz when upgrading your OS X to a new major version. After you install Quartz, first install the R package, then the gfortran package and finally the tcltk package.
