Viewing NumericMatrix From gdb [ Reply ] By: Christopher Hammond on 2015-01-21 16:17 | [forum:41818] |
I have followed the instructions for debugging C++ routines using Rcpp from gdb. This is working fine. I am having trouble actually printing or accessing elements of a NumericMatrix or NumericVector from gdb. If xin is a NumericMatrix, then gdb: p xin displays $2 = {<Rcpp::Vector<14>> = {<Rcpp::RObject> = {_vptr.RObject = 0x7fff8df4b410, m_sexp = 0x2567f20}, <Rcpp::VectorBase<14, true, Rcpp::Vector<14> >> = {<Rcpp::traits::expands_to_logical__impl<14>> = {<No data fields>}, <No data fields>}, <Rcpp::internal::eval_methods<14>> = {<No data fields>}, cache = { start = 0x31e03c39b0}}, <Rcpp::MatrixBase<14, true, Rcpp::Matrix<14> >> = {<Rcpp::traits::expands_to_logical__impl<14>> = {<No data fields>}, <No data fields>}, nrows = -537925942} p xin(1,1) does not work, nor does p R_PV(xin(1,1)) Any suggestions? |
