similar to: FW: Summary of Suggestions for poor man's parallel processing

Thanks to Luke Tierney, Agustin Lobo, Stephen Eglen, A.J. Rossini, Simon Wood and Timothy H. Keitt for responding to my question about poor man's parallel processing. Much of the substantive material was cc'ed to r-help already, but my take is as follows. 1) Currently, there is nothing "simple" for solving my problem. 2) I thought that Timothy Keitt's description of the use

Almost all of the heavy crunching I do in R is like: > for(i in long.list){ + do.something(i) + } > collect.results() Since all the invocations of do.something are independent of one another, there is no reason that I can't run them in parallel. Since my machine has four processors, a natural way to do this is to divide up long.list into 4 pieces and then start 4 jobs, each of which

The inconsistency is that you use $<- to set the column, then [[<- to change it. Had you tried to set the column by x[[1]] <- as.character(x[[1]]) you would have seen the problem immediately (it does not work as you would have intended). If you want to be sure to turn off conversion to factor, you need to set the column to class "AsIs". My belief is that will behave

Hi, I see some weird behavior when loading a specific dataframe after changing the value of an enviroment variable using Sys.putenv(). Alas, I can't reproduce it from an arbitrary dataframe.

As cool and wonderful as the package checking tools for R are, I sometimes am stymied when trying to track down a problem. For example, I occasionally see error messages when running R CMD check like the following: [...] * checking Rd files ... OK * checking for undocumented objects ... ERROR * in parse(file, n, text, prompt) : syntax error on line 932 * in undoc(dir =

For those who are interested, I've finished release of 0.4 of pmg and have placed it on my website at http://www.math.csi.cuny.edu/Statistics/R/pmg. The pmg package provides some GUI elements using the RGtk package and friends: RGtk, OOP, RGtkExtra, RGtkHTML, RGdkPixbuf, RGtkViewers and REventLoop from www.omegahat.org and gtkDevice from CRAN. (These require a form of UNIX such as linux, OS

We're mostly Cisco CallManager with some SIP and Asterisk. I want someone at one of our locations to be able to dial and number and have Asterisk simultaneously dial several Call-Manager extensions which are set to auto-answer and talk into the phone creating a sort of paging system. We have informacast, but it is too cumbersome for the users. I know Asterisk can ring several phones at the

The help for options says: echo: logical. Only used in non-interactive mode, when it controls whether input is echoed. Command-line options `--quiet' and `--slave' set this initially to `FALSE'. I don't think that this is correct for me. Consider the following session: mica|junk> ls test.R mica|junk> cat test.R cat("Why was this command

I often get warnings like the following when running R CMD check [...] * checking for code/documentation mismatches ...

I tried ot build rpvm in my own makefile. But runs into some linker errors like e.g. undefined reference to `_R_alloc' My enviornment looks like this: CYGWIN pvm 3.4 compiled under cygwin myself R installed from the rw2001.exe setup file. I guess that the R under rw2001.exe was build with some other compiler? I then tried to compile R myself under CYGWIN but runs into the following

Hello R enthusiasts, I am working with a Fedora Core 6 OS and R 2.5. I have just finished loading PVM on my test cluster and this is working properly. Also, rpvm has been loaded in R. However, when I try to load my test program, I receive this error: Loading required package: rpvm Error in dyn.load(x, as.logical(local), as.logical(now)) ; unable to load shared library

Hi, I'm wondering what the best option to obtain a high availability asterisk server is. I currently use a TE410P (4 x E1) card. I'm thinking of 2 different solutions: - 2 servers configured with Heartbeat + DRBD (drbd mainly for voicemail....) and the E1 span plugged to the 2 servers (with a TE410P in each server). - 2 servers configures with Heartbeat + DRBD with the E1 span hooked

Hi, We are considering organizing some of our ascii files with multiple "column names" like so: a.long.but.complete.name a.different.complex.name short.name.1 short.name.2 1 7 2 8 3 9 [more data] The basic idea is that we want to keep, in one location, both a long descriptive name of each variable (in row 1) and a short convenient name (in row 2). I could imagine keeping other

Hi all, I've tried researching this, and so far, have struggled to find any contemporary information on the issue, so I do apologise if asking this irritates people who have answered this before. I have managed to set up Asterisk 1.8 on the web server here. I have two softphones (Ekiga) able to communicate with it. So far so good. I'm now curious to see if I can link it with the PSTN

I've trying to fix the check error in rpvm package. Right now on my Mac, I use darwinport to install PVM and I can get rpvm to pass the check using 'R -arch x86_64 CMD check'. However the default 'R CMD check' uses i386 which fails since PVM is built for x86_64 only. So is there a way to ensure proper architecture is used that matches that of the external library like PVM?

Dear Friends, I'm trying to learn to use parallel computation using snow & rpvm Now, I have two boxes: 1) Pentium 4, pvm 3.4.5, R 2.2.0 with FreeBSD 5.4 (box uffbsd); 2) PowerPC, pvm 3.4.5, R 2.1.1 with Debian Linux latest stable (box powerpclinux); I'm using the instructions in (found in snow.pdf) http://www.stat.uiowa. edu/~luke/R/cluster/cluster.html.
