Calling Functions in the R Language

Transfer from a SAS Source to an R Destination

The following table summarizes the frequently used methods that copy from a SAS source to an R destination. Several of these modules and methods are used in the program in the next section. For details of the transfer process and a full list of methods that transfer data, see the "Accessing R" chapter in the online Help.

Table 11.1: Transferring from a SAS Source to an R Destination

Method or Module	SAS Source	R Destination
ExportDataSetToR	SAS data set	R data frame
ExportMatrixToR	SAS/IML matrix	R matrix
DataObject.ExportToR	DataObject	R data frame

As a simple example, the following program transfers a data set from the Sashelp libref into an R data frame named df. The program then submits an R statement that displays the names of the variables in the data frame.

run ExportDataSetToR("Sashelp.Class", "df" );
submit / R;
   names(df);
endsubmit;

The R names function produces the output shown in Figure 11.2.
