Suppose we have a data file containing: "Smith, John", 120, 90 "Thomson, Peter", 110, 85 there are 3 variables in it. If we use x <- read.table("tmp.txt", sep=",") to read the data to a data.frame, the result will be 4 columns. Splus 4.0 have no problem with this kind of data. Li Dongfeng

Hi, I am having trouble building wine. I can't seem to get libopegl32.so build correctly. Where it comes down to it doesn't link to libGL.*.so. I am trying to build wine on debian unstable with nvidia stuff. checking for XvShmCreateImage in -lXv... yes checking for GL/gl.h... yes checking for GL/glx.h... yes checking for GL/glext.h... yes checking for up-to-date OpenGL version... yes

Hi there, I have just found that the ``attach'' function can get you into trouble when called many times. For example, you have a simulation routine called ``f()'', in which you used ``attach'' and no corresponding ``detach''. Then you call this function many times. You will find that the system performance get slower and slower, because you are making the R

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,

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?

ELLCC is a compilation tool chain based on clang/LLVM, libc++ and the musl standard C library for Linux. Recently I was asked if ELLCC pre-built binaries could be used to build clang/LLVM TOT. It turns out that it can with some simple patches. This is a simple way to bootstrap clang/LLVM on an arbitrary Linux system that either doesn't have GCC or has a version of GCC that is too old to

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

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'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

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

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.

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,

Hi there, I would like to enable the desktop user to create shared folders, for example using protocols like Samba, nfs and sftp. For the user to make this possible, the user needs (on a Linux machine configured with the defaults of most current Linux distributions) root privileges. However. In a desktop environment, in my humble opinion the possibility for a normal user to configure a simple

Hi All - I notice that most of the Rails team are using Mac OS X and TextMate for Ruby development. I too am working on Mac OS X and trying TextMate and (shudder?) EMacs. I was wondering about version control. Are folks using Subversion? If so, are they using a graphical client? Which one do they recommend? Yours, Jordan -- Posted via http://www.ruby-forum.com/.

Hi, I am trying the lattice graphics in R. Let's say, such a little experiment in file myprog.r: f <- function(){ x <- 1:10 y <- x^2 xyplot(y ~ x) } f() Then I run the program: > source("myprog.r") but nothing happens. Manully run f() at the command line: > f() then the figure is shown. This seems to be a bug only associated with lattice graphics, the

Hi, I compiled R 1.1.0 source on SUN Sparc solaric 2.5.1, using gcc 2.95.2. I need to use R to publish graphics to the web, the NEWS in this version said that there is a new png() device on X11(). But when I tried > png() I got this error. Error in png() : No png support in this version of R Can anyone tell me how to compile png support on solaris/unix? The new bitmap() device
