RTFBS can store MS objects in R's memory, or C's memory for efficency reasons. This function transforms an MS object whose data is stored in memory within R into an MS object whose data is stored in C's memory. The result is a new MS object in R whose data is stored in C memory. Copying an MS object from R into C is performed automatically by RTFBS when it needs to run C code. The user will probably not need to call this function.
An MS object stored by value in R
an MS object containing only a pointer to an object created in C which contains the data.
