Can anyone point me in the right direction of figuring out what downweight() is doing? I am using vegan to perform CCA on diatom assemblage data. I have a lot of rare species, so I want to reduce the influence of rare species in my CCA. I have read that some authors reduce rare species by only including species with an abundance of at least 1% in at least one sample (other authors use 5% as a rule, but this removes at least half my species). If I code it as foll...

Dear all, I was doing an experiment to disprove some theory therefore performing lot of random simulation. Goal is to show the audience that although something has very rare chance to occur but it doesn't mean that event would be impossible. In this case after getting that rare event I need to show that same scenario for multiple times to explain other audience. Hence I need to somehow save that seed which generates that random numbers after doing the experimen...

I have a data frame with some factor columns. I want to drop the rows with rare factor values (and remove the factor values from the factors). E.g., frame$MyFactor takes values A 1,000 times, B 2,000 times, C 30 times and D 4 times. I want to remove all rows which assume rare values (<1%), i.e., C and D. i.e., frame <- frame[[! (frame$MyFactor %in% c("A",&quot...

...titioning, fission, or whatever you might call it? I'm still developing a good sense for this, but let me lay out some observations. Fair warning, this is going to be long and rambling. Let's start with a toy example: while(c) { x = this->x; y = this->y; if (x == y) { rare(); } } If we could tell x and y were loop invariant, we could unswitch this loop. However, the rare call clobbers our view of memory, so LICM fails, and thus unswitch fails. We'd like to apply PRE here and push the reload into the loop preheader and the rare case. This currently fails...

...w=c(GridLength,GridWidth)) for(i in 1:(GridWidth*GridLength)) plot(test.som$codes[i,],type="l") Only when I use a larger grid (say for example 7*3 ) I get some of the representatives for the sin pattern. This must have something to do with the initialization of the grid, as the sin is so rare it is unlikely that I get it as a reference vector. Afterwards, because the selection for the training is also random it is also unlikely they are picked. I've been trying to modify some of the other parameters for the SOM also, but I would appreciatte some input to keep me going until I receiv...

New .deb packages for R 3.0.0 on Raring Ringtail (13.04) are available on both [CRAN](http://cran.us.r-project.org/bin/linux/ubuntu/) and my [Launchpad PPA](https://launchpad.net/~marutter/+archive/rrutter). Some notes for this release. - The initial build for Raring Ringtail did not come with Tcl/Tk being supported. This issue has been addressed and the current release supports Tcl/Tk. -

I have several too and I also see this problem on occasion. Like you say, it is fairly rare and I can't pinpoint a cause or tell if it is a symptom of something else. I think I wrote to tech support about it but never heard anything. I'm wondering how long they will continue to support the phone. -Nate > -----Original Message----- > From: Jerry Geis [mailto:geisj@pages...

Hello, I am reaching out for a problem I have seem to hit wall on. I am trying to build a rare event model:- Default event occurred in NY/NJ area. Some key statistics: 138 default aka 4bp (.04%). Obviously my logistic and robust logistic models are failing Hosmer GOF tests and so I am thinking about bootstrapping data. I found a great read on R-help, but I was wondering if someone can help...

Sir, This mail to signal a problem : R graphics don't work on my Dell laptop with the processor Intel? Core? i7-2640M CPU @ 2.80GHz ? 4 and graphic card Intel? Sandybridge Mobile x86/MMX/SSE2 since the update with Ubuntu raring ringtail. It works perfectly with the previous version ubuntu quantal and previous versions. Thank you for your attention Sincerely yours C. Krzisch

...with the Evolution Calendar (which I do not use) crashing, when I exited from Evolution, has almost completely disappeared. One or more of the updates since the huge update eliminated most of that problem. It seems to only happen now when I am going to log out of my Desktop or shut it down and only rarely.

I observed about +6% performance improvement in one of c++ tests in spec2006 in AArch64 by avoiding inlining functions in exception handling region. I guess this is not really rare because programers often make small methods with throw statement like fCallee() in below sample c++ code.
