R and SAS are different products/Languages used in Analytics , both can be used to solve Analytic problems . SAS has been widely used in Datawarehousing systems too. R is a open source , you can get it for Free where as SAS is a licensed tool. Some prefer R whereas some prefer SAS . If you're focusing only on SAS programming , then you don't have to b worry about learning R.
