Data scientists use statistical models to predict future events based on current and historical data. R is an open source programming language for statistical modeling and graphics. Users can write scripts and table operators in R to run inside Teradata Database. Both methods access data stored in Teradata Database and process the data using R data analysis tools. For more information on R table operators, see Teradata Vantage™ - SQL External Routine Programming , B035-1147 .
