Frank, Both RZope and Rho solve this problem. RZope (http://www.analytics.washington.edu/statcomp/projects/rzope/)solves it by using *nix's fork command, which takes as much time as a memcopy. Rho(http://rho-project.org) solves it by maintaining a pool of idling R processes, which it maintains active & can pull to do a calculation immediately. Both of these are pretty

Hi, Is there any existing functions to open an HTTP connection and HTTP POST some R data? like <form method="post" enctype="multipart/form-data"> etc. </form> but within R.

Dear R-devel, Is there a way to find the size in bytes of a save() command --before-- the file has been saved? If not, can anyone point me to some resources on XDR so I can find a way to calculate it?

Hi, Here's some suggestions for troubleshooting the install. The CLASSPATH needs to be $SJAVA_HOME/org/omegahat/Jars/Environment.jar, $SJAVA_HOME/org/omegahat/Jars/antlr.jar $SJAVA_HOME/org/omegahat/Jars/jas.jar $SJAVA_HOME. This allows the java compiler/interpreter to find 1)the ROmegahatInterpreter and REvaluator classes(in a org/omegahat/R/Java tree under SJava 2)& the

I'll take a risk following Uwe's wonderful response to that advert. I'm looking for someone, perhaps particularly a stats student, who might want to do a piece of work with me on using R to present and analyse routine data that psychotherapists might submit on a cgi-bin interface and perhaps cross-referencing that against some largish referential data to which I have access.

I am currently the only use-R at my company, but they are considering buy a more powerful server and letting multiple people use it. They asked me if R supports client-server setups. I know S+ has a server version that does that. I didn't find anything about that on CRAN, but hopefully someone can correct me. I did see some stuff about R web servers

Hi, I just installed R in Windows, it seems to me that R is a standalone desktop application. Do you know if R has its server version which could handle multi-users, have several distinct R sessions and their own variables in Unix or Windows? I saw OpenStatServer, RStatServer available, can those handle multi-sessions? Thanks Mike [[alternative HTML version deleted]]

I am writing a function to make a multi-part form request with binary data. I am running R 1.8.1 on Linux ReadHat. The sockectConnection is initialized with open="a+b" and blocking=TRUE. After writing the Post request using writeChar and writeBin and flushing the connection I use socketSelect to check if the socketConnection is availabe for reading. This call consistently takes 15

Hi, A few comments from a fairly experienced R user who worked for several years on a R-based bioinformatics analysis framework. I don't want to misrepresent anyone's views, but... There are real disadvantages to the "objects-as-C-structs" and functions/methods which "mutate" based on argument type. i.e. S4. (1)Novices simply don't understand it.

Hello all, I'm trying to run SJava package (0.65 modified downloaded from : http://stats.math.uni-augsburg.de/iPlots/alpha/) on windows NT 2000 and R 1.8.01. I have also downloaded the PDF Calling R from Java and when I want to execute the following code: import org.omegahat.R.Java.*; import java.io.*; public class Essai{ public static void main (String [] args) { REvaluator e = new

Rcgi is a CGI WWW interface to R. Recent versions have the ability to use "embedded code": you can mix user input and code, allowing the HTML author to do anything from load in data sets to enter most of the commands for users without writing CGI scripts. Graphical output is possible in PostScript or GIF formats and the executed code is presented to the user for revision.

Hello All, ?I have a Dell Vostro 1550 laptop. i3 core, 64 bit, 8gb ram etc etc. I had a nic interface, but some how the wired nic is not working. So I am trying to use the BCM 4313 wireless chip, of this system, to connect to the internet. ?I have Cent os 6.5 (64 bit) installed with the required libraries and kernel sources, headers etc. I got the source code of the driver,

Dear All, I am writing to ask if you would please test our first public release of Rcgi, a CGI WWW interface to R. We've added a few new tricks to what has gone before, the most interesting of which is the ability to use "embedded code": you can mix user input and code, allowing the HTML author to do anything from load in data sets to enter most of the commands for users without

As a follow-up, I have traced the PRI connection and discovered that calls hung up by a local BCM voice station (analog, digital, whatever) send a disconnect with a clear cause of 1 (Number not assigned) instead of a normal clear cause of 16. Calls forwarded through the BCM disconnect with the normal clear cause. I have kludged up a fix to change all clear causes below 2 to 16 (I placed

I am keen to look at Rcgi as I want to put up some simple bits of R to do prescribed tasks on HTML form input. Rweb is overkill and worryingly flexible for what I want and it sounds as if Rcgi is more what I need. However, I can't get any of the URLs I've found for it to work over the last few days. Does anyone have a recent copy they could Email me or a working URL for it? TIA,

Greetings! Has anyone - or is it even possible to - set up Asterisk with multiple SIP Clients to a Nortel BCM switch? The intent is to set up an Asterisk IVR behind the BCM, have the BCM route calls to Asterisk IVR and then transfer calls to one of two queues in the BCM based on ANI and some database information. The wiki (and Google) only mentions PRI, Line-side T1 or H.323 interfaces to the

Hey All ! I ended up browsing to Eric Hodel''s blog the other night, and found his entry about the new cache_model and memcache-client. Now, it looks like it''s "officially" out in the open: http://weblog.rubyonrails.com/articles/2006/01/20/caching-models-with-memcached In my application, I''ve been staying away from caching my models, and instead just doing
