similar to: "Bayesian change point" package bcp 2.2.0 available

Version 2.2.0 of package bcp is now available.? It replaces the suggests of NetWorkSpaces (previously used for optional parallel MCMC) with the dependency on package foreach, giving greater flexibility and supporting a wider range of parallel backends (see doSNOW, doMC, etc...). For those unfamiliar with foreach (thanks to Steve Weston for this contribution), it's a beautiful and highly

foreach (or virtually anything you might use for concurrent programming) only really makes sense if the work the "clients" are doing is substantial enough to overwhelm the communication overhead. And there are many ways to accomplish the same task more or less efficiently (for example, doing blocks of tasks in chunks rather than passing each one as an individual job). But more to the

The CRAN package snow is superseded by the parallel package which is distributed with R since version 2.14.0.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!

Dear list, When I run an R CMD check --as-cran on my package (pROC) I get the following note: > Uses the superseded package: ?doSNOW? The fact that it uses the doSNOW package is correct as I have the following example in an .Rd file: > #ifdef windows > if (require(doSNOW)) { > registerDoSNOW(cl <- makeCluster(2, type = "SOCK")) > ci(roc2,

I apologize in advance for probably missing something obvious, but if someone could point me in the right direction I'd be grateful. This NOTE is not unique to our package (I list a few others, below). Package bcp has several Suggests (strucchange, for example). Then in an Rd file, we have if (require(strucchange)) { # Doing some examples making use of strucchange } The CRAN check

Hi Jay Emerson, Our Intention is to primarily optimize "R" to utilize the Parallel Processing Capabilities of CELL BE Processor.(has any work been done in this area?) We have huge pages(of size 1MB 16MB ) available in the system and as you pointed out our data is also in the GB ranges.So the idea is if Vectors of this huge size are allocated from Huge Pages the performance will

Hi- I am interested in running the BCP model in R and I am also new to R. My main issue is how to ask a specific questions within the script for this model, i.e., how one or multiple dependent factors (blue) are interact with the dependent factor (yellow), and nest the question do categorical factors (green) changes those interactions. I have attached some fake data in the link below with

Hello, I am trying to run a small example with foreach, but I am having some problems. Here is the code: *library(doMC) registerDoMC() zappa = list() frank = list() foreach (i = 1:4) %dopar% { zappa[[i]] = kmeans (iris[-5],4) frank[[i]] = warnings() }* The code runs without error. However the zappa and frank will be empty lists. If I use regular *for *instead, the list will be filled up

This is something I would like to share, and if possible, get feedback. I am working on a calendar webapp - something to replace Google Calendar for webmasters that do not like the idea of their users being tracked. Part of that project involves time zone selection, and time zone selection I want internationalized, and I found the existing functions in PHP to be extremely poor. As in the php

Hello, i have ported the BCP (Bride Control Protocol) patch for pppd 2.4.1 mentioned in http://lists.osdl.org/pipermail/bridge/2004-September/000619.html to pppd 2.4.2. The kernel patch still works without problems with kernel 2.4.30. Perhaps someone else could use this patch ... Here again some documentation i have found about the BCP patch somewere else: When pppd negotiates BCP, it tells

We are building a package, and want to create S4 methods for both head and mean for our own BigMatrix class. Following the recommendation in "Writing R Extensions" we use exportMethods instead of export in NAMESPACE (this is described as being "clearer"). This works for head, but not for mean. Obviously we importFrom(utils, head), but don't need to do this for mean,

Thank you very much Steve. Your suggestion works perfectly -- at least with doSEQ, doMC and doMPI.

Hello, I'm running some code that requires untaring many files in the first step. This takes a lot of time and I'd like to do this in parallel, if possible. If it's the disk reading speed that is the bottleneck I guess I should not expect an improvement, but perhaps it's the processor. So I want to try this out. I'm working on windows 7 with R 2.15.1 and the latest foreach

I was surprised to observe the following difference between 2.4.1 and 2.6.0 after a long overdue upgrade a few months ago of our departmental server. It wasn't a bug fix, but a subtle improvement. Here's the simplest example I could create. The size is excessive, on the order of the Netflix Competition data. The integer matrix is about 1.12 GB, and if coerced to numeric it is 2.24 GB.

I'm truly sorry, but I get paid to work with 2.4. My employer understands the value of giving back to the open source community, and this is what we have at the moment. Someone else is going to have to

The re-engineered bigmemory package is now available (Version 3.5 and above) on CRAN. We strongly recommend you cease using the older versions at this point. bigmemory now offers completely platform-independent support for the big.matrix class in shared memory and, optionally, as filebacked matrices for larger-than-RAM applications. We're working on updating the package vignette, and a

The long-promised revision to bigmemory has arrived, with package 4.2.3 now on CRAN. The mutexes (locks) have been extracted and will be available through package synchronicity (on R-Forge, soon to appear on CRAN). Initial versions of packages biganalytics and bigtabulate are on CRAN, and new versions which resolve the warnings and have streamlined CRAN-friendly configurations will appear

I'm using user-level security. Root can change passwords on the server. Normal users, however, either with swat or using smbpasswd directly, get the following error: machine 127.0.0.1 rejected the tconX on the IPC$ share.
