SET_LENGTH
Hello.
I'm trying to read a delimited file. I'm a little new
to the R api. In the program, I do something like
this...
/*****************************/
SEXP retval;
PROTECT(retval = allocMatrix(STRSXP,1,names.dim));
int r_eltctr = 0;
while(!myfile.eof())
{
SET_LENGTH(retval,r_eltctr+num_of_fields);
for(int i = 0;numofcolumns; ++i)
{
INTEGER(retval)[r_eltctr++] = 1;/*some
value...*/
}
++r_eltctr;
}
UNPROTECT(1);
/***************************************/
There is a segmentation fault when SET_LENGTH() is...
