ok, thats basicly the function around line 371 (transitive_closure(g, TC);). i attached also the cpp file... SEXP BGL_transitive_closure_D (SEXP num_verts_in, SEXP num_edges_in, SEXP R_edges_in ) { using namespace boost; Graph_dd g(num_verts_in, num_edges_in, R_edges_in ); Graph_dd TC; transitive_closure(g, TC); SEXP ansList, eList, vList; PROTECT(ansList = allocVector(VECSXP,2)); PROTECT(vList = allocMatrix(INTSXP, 1, num_vertices(TC))); PROTECT(eList = allocMatrix(INTSXP, 2, num_edges(TC))); Graph_dd::vertex_iterator vi, v_end; int i = 0; for (i = 0, tie(vi, v_end) = vertices(TC); vi != v_end; ++vi) { INTEGER(vList)[i++] = *vi; } Graph_dd::edge_iterator ei, e_end; for (i = 0, tie(ei, e_end) = edges(TC); ei != e_end; ++ei) { INTEGER(eList)[i++] = source(*ei, TC); INTEGER(eList)[i++] = target(*ei, TC); } SET_VECTOR_ELT(ansList,0,vList); SET_VECTOR_ELT(ansList,1,eList); UNPROTECT(3); return(ansList); } <div>On 5/12/06, Chris Jones <<a href="mailto:jonesc@hep.phy.cam.ac.uk">jonesc@hep.phy.cam.ac.uk </a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> > interfaces.cpp:371: instantiated from here This is where you should start to look, as it appears to be where the problem start from. Can you post whats in the file around this line.
