Hello, Has a function been built that will skip to a certain bit in a binary file? As of 2009 the answer was 'no': http://r.789695.n4.nabble.com/read-binary-file-seek-td900847.html https://stat.ethz.ch/pipermail/r-help/2009-May/199819.html If you feel I don't need to (like in the links above), please provide some help. (Note this is my first time working with binary files.) I'm

Hi, looking at the qemu-kvm man page, it is possible to enable snapshot for a given drive. This is what we need because we would like to start a domain with two drives, one on a file with snapshot=on and an other drive on LVM with snapshot=off. Unfortunately it seems that if you use libvirt the same option is not available when you define the domain with a XML file. I mean, I didn't find

I am very much in favor of having a div instruction with well defined div-by-zero and overflow behavior. The undefined behavior on certain values for LLVM intrinsics has been a major pain point for us in Julia, because adding the extra branches just kills performance and we know that there is an X86 instruction that just does what we want. Anyway, this was brought up briefly above, but want to

As the discussion has progressed and I've spent more time thinking about the topic, I find myself less and less enthused about the current proposal. I'm in full support of having idiomatic ways to express safe division, but I'm starting to doubt that using an intrinsic is the right way at the moment. One case I find myself thinking about is how one would combine profiling

I suppose everybody who makes a package for the first time thinks "I can change anything!" and then runs into this same question. Has anybody written out information on how a package can override functions in R base in the R 2.14 (mandatory NAMESPACE era)? Suppose I want to alphabetize variables in a summary.data.frame, or return the standard deviation with the mean in summary output.
