calculating the mode in R...
Dear R users I?m aware that the package ?modest? is useful to find the mode in an array. However, I?d like to know if someone has translated the ?mode? function built-in in MATLAB into R language.

R OS X panther? (PR#5529)
I have just used the RAqua.pkg to install R, and it doesn't work! I have Mac OS X 10.3, and the old version of R works OK, but the .pkg thing installed, and then when I double-click on the "StartR" application nothing happens. Nothing at all, no little icon bobbing up and down in the dock, just nothing. What have I done wrong? I didn't have to install the other packages

can we help with libvorbis release for CVE fixes?
Hi Ralph, Thank you for your reply! For context -- we consider reported CVEs as bugs even if it's in a third-party library we use (such as libvorbis). We first determine if the CVE is something that would impact our customer workflows. In this case because of our use of libvorbis for audio I/O, it does impact our customers so we need to resolve the CVE as soon as possible. In the

[LLVMdev] [RFC] YAML I/O
I've been working on reading and writing yaml encoded documents for the lld project. Michael Spencer added the YAMLParser.h functionality to llvm/Support to help in parsing yaml documents. That parser greatly helps at the syntax level, but you still need to hand write a lot of semantic checking and then convert the various node types in to something usable. I've developed a layer on

About Clang llvm PGO
Thanks for testing out LLVM PGO and evaluated the performance. We are currently still more focused on infrastructure improvement which is the foundation for performance improvement. We are making great progress in this direction, but there are still some key missing pieces such as profile data in inliner etc. We are working on that. Once those are done, more focus will be on making more passes
