similar to: using foreach function with gtrendsR

Dear R helpers, I have what another member on this forum described as an embarrassingly parallel problem. I am trying to fit models on subsets of some data based on unique combinations of two id factors in the dataset. Total number of combinations is 30^5, and this takes a long time. So, I would like fit models for each of the datasets produced by subsetting on the unique combinations, splitting

Dear R-SIG-Debian, I am using R version 3.1.2 with rstudio-server 0.98.113 on debian build 3.2.0-4-amd64 #1 SMP Debian 3.2.68-1+deb7u1 x86_64 GNU/Linux. I often use the %dopar% operator in from the foreach package to run code in parallel. However, the only other use on the box seemingly installed a few items and suddenly %dopar% will use far more than the number of cores I am specifying and

Hello all: Please help me with this "can't find object" issue. I'm trying to get leave-one-out predicted values for Beta-binomial regression. It may be the gamlss issue because the code seems to work when %do% is used. I have searched for similar issues, but haven't managed to figure it out. This is on Windows 10 platform. Thanks in advance, Nik #

If the code you are running in parallel is complicated, maybe foreach is not sophisticated enough to find all the variables you refer to. Maybe use parallel::clusterExport yourself? But be a aware that passing parameters is much safer than directly accessing globals in parallel processing, so this might just be your warning to not do that anyway. -- Sent from my phone. Please excuse my brevity.

Buenas, Quiero ver si he paralelizado correctamente el proceso. Tengo dos dataframes, A y B y quiero calcular la distancia euclídea de todas las filas de A sobre todas las filas de B. Para ello he hecho lo siguiente #cargo las librerias library(foreach) library(doParallel) #establezco el numero de clusters, en mi caso 4, ya que el procesador tiene 4 nucleos cl<-makeCluster(4)

Hi, all-- I've been working on a doParallel package to provide a foreach parallel backend for the new parallel package, but I am having trouble building the vignette. On my system, if I use the following minimal vignette (call it buggyVignette.Rnw): \documentclass[a4paper]{article} \title{Sweave Example 1} \author{Rich Calaway} \begin{document} \maketitle In this example

Thanks for the quick reply. Adding all the dependencies of doParallel (foreach, parallel, iterators) in the DESCRIPTION and in import statements in NAMESPACE resolved the build_win problems. Don't know why this is required for Windows build. Thanks again. 2015-03-05 18:22 GMT-05:00 Duncan Murdoch <murdoch.duncan at gmail.com>: > On 05/03/2015 6:16 PM, Brian G. Peterson wrote: >

Hi samba members, I've searched through google, the archives and RTFM but I can't figure this out. I've got a setup of two different offices with both their own samba PDC, wins, etc. Via OpenVPN i've set up an interdomain trust between the two domains (for now one way, but this will become two ways). One domain is called PSW with bluemoon as PDC, the other PSWINDWG with redmoon as

Hello, is there please a way to install and later update a src rpm - instead of locating and downloading that package manually? I've run: "yum install rpm-build mock yum-utils" successfully. But when I try to run "yumdownloader --source httpd", I get the error listed at the bottom of my mail. Do I maybe need to add a file to /etc/yum.repos.d/ ? I'd like to have

Allow the software channel to be created now, since methods for vblanking have been implemented. The instmem flush seems to be needed on fermi to prevent a race, but I enabled it on earlier cards too since they seem to be susceptible to the same race.

The CRAN package snow is superseded by the parallel package which is distributed with R since version 2.14.0. Here are the release notes \item There is a new package \pkg{parallel}. It incorporates (slightly revised) copies of packages \CRANpkg{multicore} and \CRANpkg{snow} (excluding MPI, PVM and NWS clusters). Code written to use the higher-level API functions in those packages should

Oh, I completely missed that one. It's very neat as it seems to work both on Windows and Unix. Thanks!

Hello: Could you please suggest the best way to become an "advanced" R programmer. I went through "R for dummies" by de Vries and Meys and I can see two ways to proceed: 1) Get a more advanced textbook. E.g. could you recommend Gentleman, "R for Bioinformatics"? 2) Because textbooks are limited and become obsolete fast, I can focus on learning state-of-the-art
