problem with "any" function
Dear R users, I have the "any" function of R  any(ind.c, ind.r, ind.sgn) all are logical factors  it works fine when any of three is true but when they are combined it doesnt work. i tried this any(ind.c, ind.r, ind.sgn,((ind.c==TRUE) & (ind.r==TRUE)), ((ind.c==TRUE) & (ind.sgn==TRUE)),((ind.r==TRUE) & (ind.sgn==TRUE)),  ((ind.c==TRUE) & (ind.r==TRU...

round() doesn't (PR#1139)
...". This is in 1.3.1 on Solaris 2.6 (full description at bottom). [Apologies for making everyone read this 3 times; my bug.report() burped.] Peter Dalgaard <p.dalgaard@biostat.ku.dk> says the problem is in fround.c, which reads in part: pow10 = R_pow_di(10., dig) ... return sgn * (intx + R_rint(x * pow10) / pow10); and (says Peter), > the problem is most likely that pow10 (== 1/100) has no finite binary > representation. Patches are welcome... I'm not up to patching C code, but I will say that a workaround is: R> round(round(100000/3, -2)) - 33300 [1] 0 a...

[RFC] Improving integer divide optimization (related to D12082)
Hello LLVM, A recent commit creates the isIntDivCheap() target query. http://reviews.llvm.org/D12082 The current approach has a couple shortcomings. First, when targets decide divide is cheap, the DAGCombiner ignores obvious power-of-2 optimizations. In the targets I know, shifts are cheaper than divides in both speed and size. The target cannot see the value in the isIntDivCheap() call, so

How to use mle or similar with integrate?
Hi I have the following formula (I hope it is clear - if no, I can try to do better the next time) h(x, a, b) = integral(0 to pi/2) ( ( integral(D/sin(alpha) to Inf) ( ( f(x, a, b) ) dx ) dalpha ) and I want to do an mle with it. I know how to use mle() and I also know about integrate(). My problem is to give the parameter values a and b to the

[PATCH v4 0/3] Btrfs: quota rescan for 3.10
The kernel side for rescan, which is needed if you want to enable qgroup tracking on a non-empty volume. The first patch splits btrfs_qgroup_account_ref into readable ans reusable units. The second patch adds the rescan implementation (refer to its commit message for a description of the algorithm). The third patch starts an automatic rescan when qgroups are enabled. It is only separated to

[PATCH v0 00/18] btfs: Subvolume Quota Groups
This is a first draft of a subvolume quota implementation. It is possible to limit subvolumes and any group of subvolumes and also to track the amount of space that will get freed when deleting snapshots. The current version is functionally incomplete, with the main missing feature being the initial scan and rescan of an existing filesystem. I put some effort into writing an introduction into

Dear Group members! Since I have set up a Samba PDC-Server (openSUSE 11.2-64bit with default package Samba 3.4.3) approx. 8 months ago, I have encountered 3 or 4 times a severe crash of Samba.

nv50: shader generation patches
Hi ! I've been trying to improve NV50 shader generation a bit the last couple of weeks, so here is what I've produced. I don't know if it's usable for you or just a pile of horrible hacks, but at least it makes some mesa demos render more correcly, p.e. the teapot (aside from mip-mapping issues of the floor texture), arbfplight, and I think the gears also didn't appear as they
