...uced two new functions .subassign2 and .subassign that are complimentary to .subset2 and .subset. * Changed x[[j]]<- assignment to x<-.subassign2(x, j, ..) to fix the problem with the previous patch. thank you ! Vladimir Dergachev

At the moment I'm just keeping an eye on cppcheck and MSVC analysis reports that I have running in visual studio.

Hey everyone! This Summer we managed to make the Clang Static Analyzer support the LLVM and LLVM-based projects with my mentors Artem Dergachev and Gabor Horvath. For a more detailed documentation please visit my final report: https://docs.google.com/document/d/1o9-xEWbzivUGKIOXp9jUNZYq0mkecd5KH5dBN5Hdlu8/ The project in a nutshell: I have fixed the most annoying false positives and added support for the custom RTTI of LLVM which became...

...x~y|z, A, layout=c(1,1,10)) The snippet above produces a valid plot in R 2.3.1, while in 2.4.0 and later I see a blank page with "x" and "y" letters on it. Can anyone else reproduce this ? thank you very much ! Vladimir Dergachev

...ssary - could anyone help ? The reason I am looking at it is that changing attributes forces duplication of the data frame and this is the largest cause of slowness of data.frames in general. thank you very much !

In various debug dumps (eg., Clang's -ast-dump), various objects (eg., Stmts and Decls in that -ast-dump) are identified by pointers. It's very reliable in the sense that no two objects would ever have the same pointer at the same time, but it's unpleasant that pointers change across runs. Having deterministic identifiers instead of pointers would aid debugging: imagine a

Thanks for the detailed explanation. So is changing the analysis technique from path sensitive (symbolic execution) analysis to some other technique bring in the soundness property ?

Hey, I am Swapnil Raj I am student in Trinity College Dublin and I am interested in working on LLVM. I am really interested in two projects listed, the first one is the extending the clang AST with template information and the second is finding smart null pointer dereferences. I am passionate about compilers and interpreters, I have written a few small language based on lambda calculus. I am

Hi How do I specify an S4 class with a slot that is potentially numeric, but NA by default? I want the slot to be NA until I calculate its value (an expensive operation, not needed for all applications). When its value is known, I will create a new object with the correct value inserted in the slot. I want "NA" to signify "not known". My attempt fails because

Excuse my ignorance (I'm not great with Git) but how would it differ for workflows of people who use a Git repository for local work but still use `svn up + patch + svn commit <list of files>` to actually land post CR or for NFC patches, while resolving conflicts during a pull into a local (non-trunk) branch manually, after the eventual full switch to GitHub? I'm aware that SVN

Hi All, My problem is about parallel execution of R-scripts. My platform is linux. A program that is written in C needs to execute multiple R-scripts simultaneously. The C program makes use of multi-threading. Each thread must initiate the execution of one script. Performance is very important. Appearantly the R C-API does not provide a mechanism for parallel execution.. It is preferred
