SAS is an integrated system of software that enables everything from data access across multiple sources to complex manipulations of data files to performance of sophisticated statistical analyses and data visualizations. Three of SAS' most popular software products that are commonly used by ecologists are Base SAS, SAS/STAT, and SAS/GRAPH. SAS is available for Windows and UNIX platforms. GUIs make SAS accessible to novice users and the command-line interface facilitates development of programs for complex data processing.
