  33. 33. but R is open source and free R has a steep learning curve Part 3: Comparing R R has lots of packages R can be customized R has the most advanced graphics R has GUI to help make learning easier R can connect to many database and data types multiple packages and ways to do the same thing by default stores memory in RAM you need much better programming skills customization needs command line you need to know which package to use
  34. 34. Comparing R and Base SAS* /SAS Stat* R is open source and free Base SAS* , SAS/Stat*, SAS/ET*, SAS/OR*, SAS/Graph* are expensive relatively because of annual licenses SAS Institute* products have dedicated support and extensive documentation by default R stores memory in RAM,so we can use the cloud you need much better programming skills Part 3: Comparing R Open source R has support from email lists, twitter, stack overflow R is slower on the desktop than base SAS for datasets ~4-5 gb R has much much better graphics You can create custom functions in R easily R has multiple GUI that are free *Copyright © 2012 SAS Institute Inc., SAS Campus Drive, Cary, North Carolina 27513, USA.
