"NettetClearly the more C++ involved the faster the QR factorization can be computed. The all C++ function solves in under a minute for matrices with up to 250 columns and 3000 rows or 600 columns and 500 rows. The R function is 2-3 times slower. Conclusion. QR is just one matrix factorization and LS is just one application of the QR. " - Left factoring c++ code
