Dear R-users, I am a dentist (so forgive me if my question looks stupid) and came across a problem when I did simulations to compare a few single level and two level regressions. The simulations were interrupted and an error message came out like 'Error in MEestimate(lmeSt, grps) : Singularity in backsolve at level 0, block 1'. My collegue suggested that this might be due to my codes

I would like to call a helper method from my View to construct a sidebar menu. The menu is contextual, so ideally I would like to do something like this: View ---- <%= sidebar_menu %> Helper ------ def sidebar_menu case _calling_view_ when ''_view_identifier_'' ... build menu... end end where ''_calling_view_'' is the key that points to the

Hi, James, Thanks for your reply. I do not think it is always true, that "mul then add" is faster than "add then mul". For example, A small immediate can be directly encoded in the instruction, but it becomes a larger one after a multiplication, which has to be loaded from the constant pool (extra memory access). So I wonder, is it possile to prevent it, via changes

Yes - this has been in InstCombine for a long time: https://github.com/llvm/llvm-project/blob/master/llvm/lib/Transforms/InstCombine/InstCombineMulDivRem.cpp#L268 We could say that the canonicalization should be reversed, but that probably uncovers more missing optimizations. The code size concern is legitimate. For example on x86, gcc asm is 2 bytes smaller on this example:

Thanks. I have checked the hook DAGCombiner::isMulAddWithConstProfitable And I think the above condition is too aggressive. // If the add only has one use, this would be OK to do. if (AddNode.getNode()->hasOneUse()) return true; Shall we make it to if (AddNode.getNode()->hasOneUse() && TargetLowering.isCheaperCommuteAddMul(......)) return true; The virtual hook

Currently we cannot support discard on block storage since ovirt may need to wipe lvs when deleting a disk, and discarding may leave unwiped user data.

Lindsay, Wouldn''t you want to use a component for this? I know components seem to be out of favor, but they seem like a perfect fit for this very thing. You could then go like: <%= render_component :controller => ''sidebar'', :action => ''home_menu'' %> The :action parameter could even be more dynamic based on your own needs. Maybe someone

Wine 0.9.53, FreeBSD 6.3-PRERELEASE. When I installed Samsung OfficeServ Manager (OSM) for Samsung PBX, it works for OSM7200, but does not works for OSM 500. When I try to run it appear small error window with 'Run-time error 3633' and program closes. OSM ver. 3.17 at 2007.10.04. These lines appear in log file: fixme:spoolsv:serv_main (0 0x0) err:iphlpapi:getRouteTable Received

Hi all, I have a strange problem with the Samba server as PDC. I periodically get the error message "No domain server was available to validate your password". But, at other times it would login fine and execute the login scripts to handle all the map drives. I don't have the slightest clue where the problem is. When the problem arise, I don't even need to do anything about it.

I installed Samba2.0.7 on my FreeBSD 4.1 box and joined an NT domain. It worked perfect until I changed the hostname today. I found that I couldn't chage the machine password if hostname length is 15. The precedure I do is 1. stop samba 2. change hostname to "abcde1234567890" 3. run smbpasswd -j DOM -r DomControl, then I get the following error message. cli_net_auth2: Error

I am using "apply" to run exact permutation t-tests by columns using the coin package. For example: library(coin) dat <- matrix(rnorm(7*35),7,35) fun <- function(x) { pvalue( independence_test(x~f, data=data.frame(x, f=factor(c(rep("a",4),rep("b",3)))), distribution = "exact")) } p.vals <- apply(dat, 2, fun) Some small-scale

Hi, folks: I need to generate all 0-1 sequences with given length,say,n=3, the ideal result would be the following matrix: 0 0 0 0 0 1 0 1 0 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1 Any help would be appreciated. -- View this message in context: http://www.nabble.com/How-to-generate-all-permutation-of-0-1-sequences-in-R--tf4704377.html#a13446919 Sent from the R help mailing list archive at Nabble.com.

Dear List, I'm interested in performing a permutation test on the interaction between a binary treatment indicator and a covariate (either continuous or categorical). I'm interested in the p-value of the interaction effect from a permutation test, and I'm using the coin package for that purpose. As I haven't seen any examples like this in the package documentation (or anywhere

Dear R users, I am looking for code to perform a permutation version of the multivariate two-sample test (difference in means). I am aware of F. Pesarin's book and website, but his single S-Plus function does not work in R (for various reasons). Has anyone adapted (or added to) PermutationTestMeans() so that it does work in R? Or do you know of an alternative implementation that does
