how to return a matrix of strings from c to R ?
I am a bit confused about usage of R internal functions. I am able to send a
char vector from C to R but not sure on how to send a vector of strings etc.
My code looks like this.
<code>
SEXP result =
PROTECT(Rf_allocMatrix(STRSXP,s->n_rics,s->n_fields));
int i,j;
for (i=0; i < s->n_rics; i++)
{
for (j=0; j < s->n_fields; j++)
{
std::string text = s->data[j][i];
result[j][i] = R_alloc( text.length(), sizeof(char));
//strcpy(result[j][i], text.c_str());
SET_STRING_ELT(result[j][i],0,Rf_mkC...
