Many research statisticians take advantage of special-purpose functions and packages written in the R language. To call an R function, the data must be accessible to R, either in a data frame or in an R matrix. This section describes how you can transfer data and statistical results (for example, fitted values or parameter estimates) between SAS and R data structures.
You can transfer data to and from the following SAS data structures:
a SAS data set in a libref
a SAS/IML matrix
an IMLPlus DataObject
In addition, you can transfer data to and from the following R data structures:
an R data frame
an R matrix
