Hello! I have a question. I am working with createFolds: folds<- trainControl(method='cv', index=createFolds(data$Score,list = TRUE)) I need to iterate over folds to extract the indexes from each fold. For example, if I do folds$index$Fold01, it contains: 5 11 17 29 44 50 52 64 65 I need to iterate over each $Fold_i to extract the indexes, but I can't do it because I

Hi, I'm having difficulties getting the news reader, Gravity, running reliably. Gravity installed okay, and I ran it for a single session. During that test, the following messages appeared many times: fixme:richedit:RichEditANSIWndProc EM_CHARFROMPOS: stub fixme:richedit:RichEditANSIWndProc EM_LINEFROMCHAR: stub fixme:richedit:RichEditANSIWndProc EM_LINEINDEX: stub

Hello All. I must be missing the really obvious here: mm <- function(d, i) median(d[i]) b1 <- boot(gravity$g, mm, R = 1000) b1 b2 <- boot(gravity$g, mm, R = 1000, strata = gravity$series) b2 Both b1 and b2 seem to have done (almost) the same thing, but it looks like the strata argument in b2 has been ignored. However, str(b1) vs str(b2) does show that the strata have been noted

Dear list, Following a recent enquiry, I've been playing with the idea of creating a colour gradient for a polygon, using the Grid package. The idea is to draw a number of stripes of different colours, using the grid.clip function. Below is my current attempt at this, library(grid) rotate.polygon <- function(g, angle=0){ # utility function, works fine matR <- matrix(c(cos(angle),

I was wondering if anyone has developed (or is developing) an implementation for gravity models (spatial interaction) in R. I conducted several searches on the CRAN website with no luck. Currently I am estimating parameters via linearization. Thank you in advance Melanie Murphy [[alternative HTML version deleted]]

I am using machine learning for one researching. I am using some classifiers with 5-fold CV . I would like to know how it is possible to extract the accuracy, for example, for KNN,neural networks and J48, for each one of 5-fold because when I apply CV to my classifier, I obtain the "mean accuracy" of 5-fold but each accuracy/error of each fold is not returned. Any help is welcome and

Adam: Thanks for putting up this page. But something is wrong. In particular, our Powerware 9135 is a three phase UPS system with THREE 480 volt outputs. So the displayed voltage is not correct -- in fact there should really be THREE voltages displayed, all around 480v. Nut developers: I am copying the NUT mailing list to see if anyone can suggest how to fix this. NUT developers, see the

There is a bug which I am seeing and a few people are reporting on the forum. The problem is a hidden window which is always rendered on top. It is always short and wide and appears near the bottom-center of the screen. Here is the output from xwininfo on that window, xprop produces nothing. xwininfo: Window id: 0x3400787 (has no name) Absolute upper-left X: 294 Absolute upper-left Y:

Dear friends, Hope you are all doing well and having a great weekend. I have data that was collected on specific gravity and spectrophotometer analysis for 26 mixtures of NG (nitroglycerine), TA (triacetin), and 2 NDPA (2 - nitrodiphenylamine). In the dataset, x1 = %NG, x2 = %TA, and x3 = %2 NDPA. The response variable is the specific gravity, and the rest of the variables are the predictors.

Hi, I'm having problems with windows which open off-screen and are thus inaccessible. Until recently, I ran my laptop with an external monitor in a dual-screen configuration. Now, I'm back to a single screen, but some wine apps appear to be trying to start up elsewhere. So, I can verify that the program is running using ps and xwininfo: wtipton 6652 26.5 2.3 2662984 36500 ?

Install letsencrypt and request a certificate specifying the webroot of your Icecast server and the host.domain: certbot-auto certonly --webroot --webroot-path /usr/share/icecast2/web/ -d icecast.domain.name Now you should have a certificate for your server, it's only in the wrong format for Icecast, copy the key and the certificate to 1 file with the following cmd: cat

Good afternoon. I would like to know if there is any function in R to do LOOCV with these classifiers: 1)SVM 2)Neural Networks 3)C4.5 ( J48) 4)KNN Thanks a lot! [[alternative HTML version deleted]]

Instead of the user entering a name, I want to pass their screen name along with supplied :title and :content fields. here is what I''ve got.. f.hidden_field :author, user.screen_name here is the create method from Posts controller: def create @title = "Gravity" @user = User.find(params[:id]) # this does not work, and I don''t know why if request.post?

The cautions people have given about starting values are worth heeding. That nlxb() does well in many cases is useful, but not foolproof. And John Fox has shown that the problem can be tackled very simply too.

Hi, I'd like to use llvm from python to generate dynamically: 1) llvm functions from python expressions, eg. an "apply" operation on a c-array of floats 2) callback functions 3) calls to an external dynamic loaded c-library I've looked at the llvm python wrappers but the size of the .so module is just too massive (120Mb). However, I don't think it is actually necessary for

Does anyone know how to get procmail and dovecot to play happily together with mboxes? I'm on Centos 6.5, fully patched. I'm getting tons of lock timeouts which is killing performance. I tried using dovecot's lda from procmail, which prompted many adjustments to selinux, which I managed, but it still gives permission problems, and I haven't succeeded in getting it to deliver

Hi Jeremy, > Because that's just the way the process model works. So security nuts didn't get involved early enough? Or maybe there is some performance problem of checking on each access (at least back when model developed). Or maybe the process model is more like gravity? That is how it is, but no-one knows why. ;) > Adding a user to a group won't change the token on
