Hi, I need "mutable" objects that I can safely modify in my C code. All call interfaces, e.g. .C, .Call, etc., require you to not modify the "in" args. The description of the OOP package in R-news from Sep 2001 alludes to a possiblity of such objects, but the package itself is no longer on Omegahat and I am not sure I need the full machinery. Thanks, Vadim P.S. I wonder

I have a GNU/Linux / Unix application in which I'd like to have an R process running in a persistant state, while receiving instructions (and data) from another process, and returning results to this process. My initial thoughts are to set something up with named pipes or such, but I believe that the R process will terminate when it reads EOF (^D) from the input pipe. The client process is

Hi, Does anyone know how I can call R from within Matlab and return the result to Matlab?

Hi All, What is the current status of removing the global variables etc that is required to permit multi-threading R? I'm developing a web application tool for/using R, python (www.python.org), and Zope (www.zope.org), and it would be really convenient if I could use something like RPy to communicate with several concurrent R sessions, preferably within the same process space. -Greg

Please ignore my ignorance, I'm new to R, but starting a longish project that will use R a lot. (a computer scientist learning about stats at the same time). Did anybody alreay write a XML parser for R? XML, as we will have tons of data-interchange with all sorts of other programs and XML is good for giving meaning to raw data. I checked the FAQs and the documentation, but didn't find

The linker will eventually complain about multiple definitions of this symbol. Solution: declare

Hi everyone, I'm thinking about breaking up a large package I have to avoid loading some of the more specialised parts when it isn't necessary. The package is dependent on shared libraries. The base one will keep all of the core stuff like constructors etc and the specialised parts will need to access these. It is obviously possible to set the "local" flag to false, however

Hello. I am porting Splus library to R, which use S "graphics.h" and "device.h", the library makes a number of high resolution plots using these. Does anyone have an experience with similar porting? I don't really want to rewrite all C code, so any recommendation would be helpful. Thanks. --------------------------- Vadim Kutsyy vadim at kutsyy.com

Is there any package similar to the XML package that is able to "extract" relevant information from HTML files. Namely, I'm interested in obtained data that is represented as a HTML table, into some R-type structure.

I like to have a continuously running R process, which can receive a dataframe from a client (over TCP/IP), does some processing, and sends some data back. What is the prefered way to do this? Using the socket interface? Using omega's CORBA stuff? Does anyone has example code for doing so? Thanks for any help Regards -- Dr. Jens Oehlschl?gel-Akiyoshi Analyse MD FACTORY GmbH Gr?nstr. 15

I am writing a function to work with class I am defining. I have a question about using nargs() inside of parentheses function. nargs() shows the same for supplying 1 argument, or no arguments at all. Here is a small example: > "[.myclass"<-function(x,...) print(nargs()-1) > x<-c(1,2,3) > class(x)<-"myclass" > x[] [1] 1 > x[1] [1] 1 > x[1,2] [1] 2

Hello I am using Duncan Lang's RDCOM Client package (available on omegahat.org) under R 1.7.0 and Windows XP Pro. Is this the right forum for questions about this package? In case it is, here is my question: Instances of COM objects do not seem to terminate as expected, but leave residual processes running. For example, if I try the simple example: E <-

I've just installed Mandrake Linux, then compiled R-0.65.1 .

I have a problem with embedding R into perl. I downloaded the interface program/module from omegahat.org, and I can't seem to understand how to use it. This is all done under Win NT 4.0. If anyone have any clue or any suggestions on how to interface R into perl, I would be greatful. Please email me with comments at racerdude911 at yahoo.com Thanks Scott

Hello. The laboratory where I work has the possibility to get a Sun machine with 12 processors. My question is: can R be used to implememt parallel algorithms which take into account the several processors? Is there a way to run *threads* in R? If this is possible, would somebody share his/her experiences? Thanks. Isabel -- Isabel Cañette Iguá 4225 Centro de Matemática 11400

Hi All, I've done some work recently making some of our image analysis library callable from R and Splus. Most of the C image functions use an abstract data type, and R only sees a pointer to this. All memory allocation is done by the library. This leads to some interesting problems. I'm interested in your views about possible solutions. 1) assignment. something like a<-b, where a and
