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?

I've just installed Mandrake Linux, then compiled R-0.65.1 . Whether because I omitted some necessary items when I selected software for installion, or because they anyway needed to be loaded afterwards, I found it necessary to load the following packages in order to compile R-0.65.1 pgcc-g77-1.1.3-3mdk.i586.rpm (Fortran g77 compiler) XFree66-devel-3.3.5-3mdk.i586.rpm (X.h etc

...package? > > YG I agree with you about the parallel approach and this is what we have been building in the past year or two. R, S and Omegahat have packages that allow them to a) call methods in other applications, and b) allow other applications to call methods on R objects This uses CORBA to handle the remote method invocations, but the user is insulated from this for both a) and b) as they need only use R/S functions. The framework allows R to call an application like Gnumeric (the GNOME spreadsheet), or xgobi. However, it can also be used to have one R session invoke methods in...

Hi, I need to somehow make R communicate with another remote JAVA process which provides compute services. I have control over the communications protocol, but I would like to keep it to a standardised protocol, such as SOAP, CORBA, etc. What I would like to know is, what do other people use to do this? The nature of the communications will be low bandwidth procedure calls, with little data. (The data is stored in a DBMS). To date I have tried the RCORBA and SSOAP packages. Corba I couldn't get to compile, and soap I co...

Hi, I'm rarther curious if it is possible to interface C or Java GUIs with the underlying R statistical engine. SPLUS has something like this in S+SDK.

...r that part of the configuration of systems like Samba, nfs and sftp (openssh), and alter softwares like Nautilus. A very simple (but perhaps quick-n-dirty) solution would be to take a tool like Fedoras system-config-samba and turn it into an ORBit server, and let applications (like nautilus) talk CORBA to configure Samba. It would also be a possibility if the developers of technologies related to the desktop-world, stick their selfish heads together to create a standard for talking with the normal-user about such configuration. A lot like, on the GNOME desktop, gconf. It would be nice and easy...

Hi! Am a bit new with Wine and I've got a quite big problem. We have a couple of vendors how is using Java based programs, and i'm not able to install them under Wine. One program is also using both Java and Corba to communicate with servers. What happens is that the system is first extracting the files and when starting javaw.exe nothing happens. Any id? whats wrong?

Hi, we have a first draft of R functions reading/writing data to XML files including a rather general DTD ... which borrows heavily from the data types of a certain programming language :-) The basic idea is to create an XML standard for data exchange, together with import/export functions for as many applications as possible. We here will need R, Matlab & Octave for our research program,

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

I think we are long overdue for a revision of the header files used in R. This is going to be especially important for a clean build of the CORBA and R/Java stuff which I have been looking over Duncan's shoulder at. It will also let us integrate some of the features Duncan has had to find creative ways around and also to let us integrate things like the PROBLEM buffer problem. I would propose that we cut down to a much smaller set of in...

Hello, Following a discussion initiated on r-devel, that mentions SciViews-R and other GUIs issues for R, I would like to make comments (and would be happy if these comments would initiate interesting initiatives). A big, big problem with SciViews-R is that a part of it is written in Visual Basic 6, a M$$$$ language, not supported any more, buggy, non transposable to other platforms, etc,

Hello, I checked mail list archives and this topic came up before in March '99 (about ability of R to multithread). At that time rossini at biostat.washington.edu (Tom Rossini) suggested to check his web page in a few month as it was on his list to-do. I checked but the web page is not valid. I wanted to know if in general progress has been made in the area, or if it is planned. I was also

...39;s possible under Gnumeric, but AFAIK gnumeric won't have DB connectivity for some time and has neither the finish nor the integration of OO. We've reviewed quite a few documents that describe the integration approach and while it seems to be a bit complex (mostly due to UNO - OO's CORBA-like integration strategy), it seems to be quite doable. We envision it working ike this: - build R as a shared lib - libR.so [trivial - the R team has done this for us] - use the UNO framework to direct the writing of an IDL that allows libR.so to be linked into the OO sc runtime [time consum...

Duncan - (but sent to R-devel, for any other thoughts?) How do you envision RSPerl being used? Without having seen the details, I can think of playing with strings; is there a preferred incantation for stringification of R objects (serialization)? (actually, the main problem I'm having is that I know how I want to code something like: Robject <-

...high a level. What about simpler vectors, scalars? (I know that R/S don't have scalars, but other systems/applications do.) Can we think of a core set of "basic" data types (factors, strings, integers, etc.) from which to build on other, possibly recursive types (perhaps similar to corba's IDL basic data types or S's datadump?). Would it make sense to imagine, say xlispstat/python/java applications reading and interpreting an StatDataML document without serious difficulties? My gut feeling (which is often wrong) is that the DTD should make the data self-describing: e...
