Calling Functions in the R Language

Using R to Analyze Data in a SAS Data Set

As an alternative to the data transfer statements in the previous section, you can call the ExportDataSetToR subroutine to transfer the entire SAS data set to an R data frame. For example, you could use the following statements to create an R data frame named Class and to model the Weight variable:

run ExportDataSetToR("Sashelp.Class", "Class");
submit / R;
   Model <- lm(Weight ~ Height, data=Class, na.action="na.exclude")

The R language is case-sensitive so you must use the correct case to refer to variables in a data frame. You can use the CONTENTS function in the SAS/IML language to obtain the names and capitalization of variables in a SAS data set.
