[ALTREP] What is the meaning of the return value of Is_sorted and No_NA function?
Hi,
I would like to figure out the meaning of the return value of these two
functions. Here are the default definitions I find from R source code:
static int altreal_Is_sorted_default(SEXP x) { return UNKNOWN_SORTEDNESS; }
static int altreal_No_NA_default(SEXP x) { return 0; }
I guess the macro *UNKNOWN_SORTEDNESS *in *Is_sorted* and 0 in *No_NA
*simply means
unknown sorted/NA status of the vector, so R will loop over the vector and
find the answer. However, what should we return in these functions to
indicate whether the vector has been sorted/ co...
