R

R is a language and environment for statistical computing and graphics. R is available as Free Software under the terms of the Free Software Foundation’s GNU General Public License in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS.

R is not required for this course, but for a class project, you will need to use some kind of computer software (see the syllabus for more information); you can download it here.

RStudio is a free, open source software package that allows you to interface with the R source code. You can download it here.

You can read An Introduction to R to get started with R, if this is something that interests you.
