Implementing a single-precision class with raw
...there
don't seem to be any macros for handling raw vectors in Rdefines.h.
I've made a guess at what those macros would be and was wondering
whether my guesses were correct and/or might be included in 2.2.0:
#define NEW_RAW(n) allocVector(RAWSXP,n)
#define RAW_POINTER(x) (RAW(x))
#define AS_RAW(x) coerceVector(x,RAWSXP)
I'm not sure whether coerceVector(x,RAWSXP) will actually work. Also,
there isn't an Rf_isRaw() function, which would be useful for an
IS_RAW(x) macro.
Another issue with the "float" class is that it will run into endian
issues if it ever gets saved...

S_alloc or Calloc for return value
I am trying to write a C function to create a vector of integers that can be
used by the R calling function. I do not know the size of the vector in the
R calling function. (Well, actually, I have an upper limit on the size, but
that is so large that R cannot allocate it. What I'm doing in the function
is to do a sieving procedure, and the result will be small enough to fit
into my

how to pass 'raw' values with cfunction()?
I am having trouble handing "raw" data to a C function, using "cfunction", as demonstrated in the function and output pasted below. Can anyone suggest what I'm doing incorrectly? Thanks. Dan Kelley [Dalhousie University].
