MS From Pointer
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 on the C side to an MS object whose data is stored on the R side. The result is a new MS object containing data stored in memory on the R side copied from memory on the C side Copying an MS object from C into R enables modification of the MS object using generic R functions. To do the reverse, (copying an MS object from R to C), use the as.pointer.ms function.
An MS object stored by reference (pointer.only=TRUE)
an MS object stored in R. If src is already stored in R, returns the original object.
