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 FigureĀ 11.2.
