Dear R experts, I am having difficulty using loops productively and would like to please ask for advice. I have a dataframe of ids and groups. I would like to break down the dataframe into groups, find the unique sets of ids, then reassemble. My thought was to use a loop, but I have been unable to finish this loop in a logical way. I would like to find the unique ids for group 1, group 2,

Hello, I've set up a tinc "server" named "spitzer" in proxy arp mode, and a client "inspiron" that connects to it. inspiron runs tinc 1.0.16, spitzer runs 1.0.11. Ping and ssh from inspiron to spitzer and other hosts in the network (via spitzer) works fine. Ping and ssh from other hosts in the network to inspiron works fine (i.e. going through spitzer works

Hello, I'm confused by the subnet-up calls made by tinc. I was assuming that I'd be called once when it connects to another node. However, subnet-up appears to be called much more often than that. For example, I have the following configuration: ,---- | $ cat tinc.conf | ConnectTo = spitzer | Name = chronos | Mode = switch | | $ cat hbt/hosts/spitzer | address =

Colleagues, Platform: OS X (but issue applies to all platforms) Version: 2.8.0 I have a mixture of text and data that I am outputting via R to a pdf document (using a fixed-width font). The text contains tabs that align columns properly with a fixed-width font in a terminal window. However, when the PDF document is created, the concept of a tab is not invoked properly and columns do

Dear all: I'm trying to fit the optimal Box-Cox transformation related to nls (see the code below) for the demand of money data in Green (3th Edition) but in the last step R gives the next error message. Error en `[.data.frame`(eval(object$data), , as.character(formula(object)[[2]])[2]) : undefined columns selected. ?Any idea to solve the problem? Thanks in advance,

Hello, I am doing mcmc=10000 simulations from a posterior distribution of the parameters of a mixture of K=6 normal densities. I have mcmc by K matrices simMeans, simVars and simWeights containing the simulation output: one row for each simulation, one column for each normal component of the mixture. One thing I would like to do is a plot of the posterior predictive density. In order to do that

I have noticed quite a few changes regarding register allocation. I am wondering will there be support for radically different data structures other than the LiveIntervals, Virtual Register Map, etc? I have build a custom data structure which has it's own intermediate representation like live-intervals, but much more conducive for my allocation algorithm. I do not know if LiveIntervals can

Hi people! I'm looking for a back-end compiler for a language project of mine, LLVM looks promising, but I'd like to clear a few things up first: 1. What relation does LLVM bear with GCC; why would somebody use LLVM for a compiler back-end over GCC (aside from the Virtual Machine)? How do the goals of GCC and LLVM differ as compiler toolkits? 2. How conducive to Incremental Compilation

Dear all, I tried a simple naive Bayes classification on an artificial dataset, but I have troubles getting the predict function to work with the type="class" specification. With type= "raw", it works perfectly, but with type="class" I get following error : Error in as.vector(x, mode) : invalid 'mode' argument Data : mixture.train is a training set with 100

Dear list, Can anyone provide a package or code for estimating the parameters of a mixture of c (c >=2) univariate normal distributions? I've tried the algorithm provided by Venables & Ripley (1999) p 263, for the mixture of two normal, but I don't find the "ms" function in R. I've used nls instead, but I'm not sure if it works the same. The data I have is very

Hello! I am new to R (before used python exclusively and would actually call the R solution for this issue inside a python notebook, hope that doesn?t disqualify me right of the batch). Right now I am looking for a piece of software to fit a 1D data sample to a mixture of t-distributions. I searched quite a while already and it seems to be that this is a somehwat obscure endeavor as most

Hi, I wonder if the function "density" outputs the gaussian mixture formula that is estimated from the input data, assuming a gaussian model is used at each data point ? I want to take the derivative of the finally estimated gaussian mixture formula for further analysis. Thanks in advance for any help that you can offer me! Hui

Dear all, I am attempting to model some one-dimensional data using a mixture model of non-central Student's t distributions. However, I haven't been able to find any R package that provides this functionality. Could there be a way to "manipulate" the EM algorithms from the mixdist or mixtools package to fit the model, or do you have any other suggestions? If anyone could help

I'll comment from the perspective of someone that is in the Mesa, #dri-devel, #radeon channels myself and have watched their behaviour over the years. This is a real person that spams a load of information into a channel about their understanding of how hardware works. I have no idea what their goal is for spamming this information, could be some desire for acceptance from perceived smartness.

Dear R-help, I am doing clustering via finite mixture model. Please suggest some packages in R to find clusters via finite mixture model with continuous variables. And also I wish to verify the distributional properties of the mixture distributions by fitting the model with lognormal, gamma, exponentials etc,. Thanks in advance,  warm regards,Ms.Karunambigai M PhD Scholar Dept. of Biostatistics

If anything, these data structures are going to be simplified. For instance, VirtRegMap's

Monty, You helped me out quite a bit the other day, but I just wanted to make sure I understand something. The "ideal" way to do bit rate peeling is to have the encoder set the file up to be conducive to the peeling process, and the streamer would be the device that actually does the peeling. Am I correct in assuming, then, that the decoder would think that the file it is

HPA, now that syslinux release madness has calmed down, could you provide some info on how we syslinux-minions/wannabes can use bochs and/or qemu to run (sys|pxe|iso|ext)linux in an emulated environment thats more conducive to debugging, single-stepping, and ultimately understanding how the magic happens ? tia jimc

Hi, Is there any package that I can use to simulate the Gaussian Mixture Model , which is a mixture modeling method that is widely used in statistical learning theory. I know there is a mclust, however, I think it is a little bit different from my problem. Thanks very much.. regards. -------------------------- Peng Jiang ??
