Unexpected behavior of extract (`[`) or sapply functions
...um 1 in factor.cols = c(1,2).
Any help or suggestions would be greatly appreciated.
Sincerely,

An update on the DominatorTree and incremental dominators
Hi folks,
For the past month I’ve been working on improving the DominatorTree and
PostDominatorTree in LLVM. The RFC that explains the motivations and plans
can be found here:
http://lists.llvm.org/pipermail/llvm-dev/2017-June/114045.html .
Here’s a short summary of what changed upstream since posting it:

java binding and virtualbox-ose
I'm trying to connect to vbox hypervisor on an Ubuntu 10.04 machine
through libvirt java binding (libvirt-java-0.4.6) by simply invoking:
Connect conn = new Connect("vbox:///session", false);
but I got this exception:
libvir: warning : Failed to find the interface: Is the daemon running ?
libvir: Remote error : unable to connect to
'/var/run/libvirt/libvirt-sock':
