Using svSocket with data.table
Hi r-devel,
svSocket is working well. Short demo here of using it with data.table :
http://www.youtube.com/watch?v=rvT8XThGA8o
If you maximise and press the HD button it should be readable. There isn't
any audio.
However, svSocket is currently text based IPC using dump. Is there a
solution which will do binary and work in the same way ? Its nice that I
can make R become a server any

Error in rbind(info, getNamespaceInfo(env, "S3methods"))
Dear all,
I'm experiencing an unusual installation error for one package. Could
anyone suggest how I can best investigate this from here please? I'm sorry
this isn't very much to go on. Hopefully someone can point me in the right
direction.
The problem seems to be my library. It is large (3,418 packages) and I'd
like to avoid rebuilding it, if possible. All packages are up to

[R] data.frame() size
Hi,
Please see below for post on r-help regarding data.frame() and the
possibility of dropping rownames, for space and time reasons.
I've made some changes, attached, and it seems to be working well. I see the
expected space (90% saved) and time (10 times faster) savings. There are no
doubt some bugs, and needs more work and testing, but I thought I would post
first at this stage.

Closed-source non-free ParallelR ?
Dear R-devel,
REvolution appear to be offering ParallelR only when bundled with their R Enterprise edition. As such it appears to be non-free and closed source.
http://www.revolution-computing.com/products/parallel-r.php
Since R is GPL and not LGPL, is this a breach of the GPL ?
Below is the "GPL and ParallelR" thread from their R forum.

R socket communication
Hello, I tried to code a R socket server but I did not succeed.
The problem is that once the R socket server is created,
I call the readLines function and then R gets blocked.
The client seems to work fine since I tested it with a PERL server.
I tried many combination of params in the socketConnection but
none of them worked.
I have seen some examples where the server sends something to a
client

Import R-output into Java
Hello,
I want to import R-output via Rserve to Java, especially for the function
ctree from the package party.
Rserve is working properly.
Yet, I only get the predictions with the Java code
try{
RConnection c = new RConnection();
...
c.voidEval("modell <- ctree(...)");
REXP y = c.eval("nodes(modell,1)[[1]]$prediction");

RServe - How to use 'createReference' method?
I need to input a txt, or xls, file from a client to R, using RServe.

exec subdirectory of a package
Hello,
WRE contains the following information about the "exec" subdirectory of
a package :
"Subdirectory exec could contain additional executables the package
needs, typically scripts for interpreters such as the shell, Perl, or
Tcl. This mechanism is currently used only by a very few packages, and
still experimental."
I think it would be useful to expand "very

Rserve (Anyone?)
REXP has an asBytes() method. Will this capture the output of an R plot
function if a proper graphics device is used? It appears R insists on
sending plot output to a file. Kind of strange since it insists on loading
all your data into memory before it can do anything.
If so then does anyone know what this would be? I prefer png or jpeg.
Example:
c is an RConnection

some questions about startup Rserve
I realize the communication between R and Java with Rserve in my
dissertation, but i can not run the Rserve by double click of Rserve.exe,
and also i can't realize backstage running of Rserve by technique of
Multi-thread in Java. Can anyone tell me why?
So, before i run the Java, i must run the R manually, then input
"Rserve()" or "system("Rserve")". This

Rserve and R to R communication
Dear All,
The "clients.txt" file of the latest Rserve package, by Simon Urbanek,
says, regarding its R client,
"(...) a simple R client, i.e. it allows you to connect to Rserve from
R itself. It is very simple and limited, because Rserve was not
primarily meant for R-to-R communication (there are better ways to do
that), but it is useful for quick interactive connection to an

Where to get support for Rserve?
Hello,
I'm using Rserve with Java and although it works OK for 50 or 60 requests, eventually Rserve simply stops responding and I have to force-quit and restart Rserve. During this time the JVM is fine and Tomcat (app server) is fine, too.
The basic Java code does this:

1. Create an R Connection
2. Execute an R Script via Rserve "eval"
