Dear Wiz[R]ds, I am deeply grateful for the help from Duncan Murdoch, Gray Calhoun, and others. We are almost there. For whatever reason, I can't change the symbol from a circle to a triangle in the upright posture plots. Any ideas? I have included the problem in full. # tritiated (3H)-Norepinephrine(NE) disappearance from plasma # concentrations supine and upright # supine datasu <-

I have huge list of edges with weights. a1 b1 w1 a2 b2 w2 a3 b3 w3 a1 b1 w4 a3 b1 w5 I have to convert it into 2 dim matrix b1 b2 b3 a1 max(w1,w4) 0 0 a2 0 w2 0 a3 w5 0 w3 if edges repeated take the maximum weights. How do this efficiently without using for loop? Any idea. thanks Avi [[alternative

Hi: I hope to cut all backedges of MachineFunction CFG, then topological sort MachineBasicBlocks. 1. MachineDominatorTree *domintree = new MachineDominatorTree(); domintree->runOnMachineFunction(mf); 2. Then travel mf one by one. When domintree->dominates(next,current) is true, there is a backedge from current node to next node. move this backedge form CFG. But I find A LOOP in

Hi, Dear Boissinot: 1. When I have irreducible CFG, I travel its nodes by DFS. search backedge for every node. After I finish one node, push it into a stack. [0, 1, 2, M] <---push. [0, 1, 2, M,...N] <---push. When resolving node M, find a edge from node N to node M, N is not in stack(M < N), It is a backedge. N is in stack(M > N), It is NOT a backedge.

Hi:    I want to do some optimization on MachineLoop. So I want to get MachineLoopInfo from MachineFunction. I reference MachineLICM.cpp. So I try to write a pass in Target/mytarget directory. I find there is Error. llvm/include/llvm/PassAnalysisSupport.h:198: AnalysisType& llvm::Pass::getAnalysisID(const llvm::PassInfo*) const [with AnalysisType = llvm::MachineLoopInfo]: Assertion

I don't know why, but for my case, I reduced the tinc topology from a complex one(which provide layered redundancy) to a very simpled one(one connection), and that connection drop disappeared. Later, let me draw the topology and share the config to you to see if there's any findings of the cause. Guus Sliepen <guus at tinc-vpn.org>于2017年9月14日 周四上午3:20写道： > On Wed, Sep 13, 2017

I am splitting a one BB loop into two BB. Basically, the one loop BB has 3 incoming values, one form back edge two from other edges. I want to extract the PHIs from the other two edges out into it's own BB and delete that from the loop, then redirect the backedge to the loopbody (non extracted portion) and create a new PHI coming from the extracted BB and the backedge. I can do this;

I there, I have some trouble to do working caller id name for outgoing calls on the PRI we just installed. Caller id name work on incoming calls only. Caller id number work on incoming and outgoing calls. The provider, Goup Telecom, said that's in what i'm sending. They said that I send the cid name in ascii code and to do it working, I need to send it in hex. So I take some traces

Here is the code snippet that I am using to create the PHIs in the loop according to the PHIs in the new preheader. At this point I have already redirected the loop backedge and removed the preheader from the loop. for (BasicBlock::iterator II = loopHeaderBB->begin(); (PN=dyn_cast<PHINode>(II)); ++II) { // remove loop back PHI and add it to split BB

Hello, I finally run my measurement model in sem - successfully. Now, I am trying to print out the path diagram that is based on the results - but for some reason it's not working. Below is my script - but the problem is probably in my very last line: # ANALYSIS OF ANXIETY, DEPRESSION, AND FEAR - LISREL P.31 library(sem) # Creating the ANXIETY, DEPRESSION, AND FEAR intercorrelation matrix

Hi all, In order to identify loops I'm using the DILexicalScope metadata attached to the loop latch, but with some combinations of optimisations that metadata seems to disappear. For example, when -simplifycfg removes a block because it only contains a branch, and -loop-simplify recreates that block because it turned out to be a back-edge of some loop, the metadata gets removed.

Dear List, I neeed a grouped list with two sort of categorical data. I have a data .frame like this. year cat. b c 1 2006 a1 125 212 2 2006 a2 256 212 3 2005 a1 14 12 4 2004 a3 565 123 5 2004 a2 156 789 6 2005 a1 1 456 7 2003 a2 786 123 8 2003 a1 421 569 9 2002 a2 425 245 I need a list with the sum of b and c for every year and every cat (a1, a2 or a3) in this year. I had used the tapply

Hi R users, I am trying to omit rows of data based on partial matches an example of my data (seal_dist) is below: A quick break down of my coding and why I need to answer this - I am dealing with a colony of seals where for example A1 is a female with pup and A1.1 is that female's pup, the important part of the data here is DIST which tells the distance between one seal (ID) and another

Hi all,I know this topic has came up multiple times, but I've never fully understand the apply() function. Anyway, I'm here asking for your help again to convert this loop to apply(). I have 2 data frames with the following information: a1 is the fragment that is need to be covered, a2 is the probes that cover the specific fragment. I need to count the number of probes cover every given

Dear R-devels, We have encountered a problem concerning a dead lock in the dependency graph: We have two packages A1 and A2 where A2 extends A1. We have one package vignette for both packages, but which should be included into package A1. So in the "suggests" field of the DESCRIPTION file of A1 we suggest A2 to be able to produce the vignette at build/install time. On the other hand

Hello. This is a follow-up to a question I posted last week. With some previous suggestions from the R-help community, I have been able to plot survival (, hazard, and density) curves using published data for Siler hazard parameters from a number of ethnographic populations. Can the function below be modified, perhaps with a "for" statement, so that multiple curves (different line
