2. In this video, I'm going to briefly show how you can install R on the Mac. It's a very simple process, it only takes a few steps.

Most Unix / Linux operating system distributions, as well as Mac OS X, include Tcl/Tk. If not already installed, you can use your system's package manager to install the appropriate packages. For example, on a Debian system, you can type apt-get install tcl. Note than some components, even including Tk, man pages and C libraries.
