Comparative Methods in R How To

Getting started with R:

R is freely available statistical software, which can be run in various environments (MacOSX, Windows, Linux). For a general description of R, visit its its introductory page. To download R, go to its homepage and select one of the CRAN mirrors. Most users will want to choose a precompiled binary distributions for their system (Mac, Windows, Linux). For PC users, select the "base" subdirectory and download and run the setup program (.exe file). MAC users will download the .dmg file and double-click the icon to install the program.

In order to run comparative analyses in R, the user will need to download one or more additional packages. To install R packages, open R (by double-clicking the desktop icon, via the start menu for PC users, or within the applications folder for Mac users). The first window users will see is the R Console. Mac users can download packages via the Package Installer in the Packages & Data menu. PC users can download packages by selecting install packages from the Packages menu.
