There is some historical precedence for fixing the problem with VS lower_bound by changing the LLVM source - when I first got LLVM to compile with Visual Studio, patches for unsymmetric operator < were accepted into the LLVM repo, and I believe it's been done several times after that as well. m. >From: Ahmed Bougacha >Sent: Friday, July 05, 2013 1:43 AM >To: Benoit Perrot

Dear R-Help list: I'm using the Matrix library to operate on 600 X ~5000 element unsymmetrical sparse arrays. So far, so good, but if I find I need more speed or functionality, how hard would it be to utilize other sparse matrix toolsets from within R, say MUMPS, PARDISO or UMFPACK, that do not have explicit R interfaces? More information on these is available here www.cise.ufl.edu/resea...

Hi all, A few days ago, there was a report of LLVM not compiling on VS 2008, because of asymmetric std::lower_bound comparators not supported there. As noted by a few people, maybe it's time to drop VS 2008 compatibility and move the requirements to VS 2010? While there, what about going further and starting using C++11? Now seems as good a time as ever; my takeaway from that few months old

Hello, I have just updated my svn copy of the llvm/clang repositories after quite a long time of inactivity, and found it not compiling on Windows with Visual Studio 2008. The incriminated file is: llvm/lib/MC/MCModule.cpp Where several calls to "std::lower_bound" are made, like: atom_iterator I = std::lower_bound(atom_begin(), atom_end(),

I'm in favor of dropping VS 2008 support (in fact, I thought we had already talked about doing that, but perhaps I am remembering incorrectly). I think C++11 support should be a separate discussion than dropping VS 2008 support because it's likely to be a bit more in-depth, but I'm in favor of it. ~Aaron On Sat, Jul 6, 2013 at 12:05 PM, Ahmed Bougacha <ahmed.bougacha at

This thread reveals that R has some holes in the solution of some of the linear algebra problems that may arise. It looks like Jim Ramsay used a quick and dirty approach to the generalized eigenproblem by using B^(-1) %*% A, which is usually not too successful due to issues with condition of B and making a symmetric/Hermitian problem unsymmetric. In short, the problem is stated as follows:

Before I reinvent the wheel, I have need for a relatively straightforward crosstabulation (2 x n) function. I know that R has table(), ftable(), xtabs(), and summary(xtabs()), but none of these produce a fully "tricked" out cross-tabulation with marginal totals, expected cell frequencies, and an array of statistics about the contingency table. Is there a more complete (something
