This email isn't asking for assistance, but I thought R-help readers would find it interesting. This week we offered a half-day introduction to R for researchers at Augsburg University. The response was astonishing. Although Augsburg has no medical faculty and no engineers, there was far too much demand, with interest from every faculty (barring theology, "for one small

I encountered several strange issues when linking to R.dll on Windows and I wonder if anyone of the Windows savvy-folks here had seen some of the issues before and have some explanation. My Rserve links to R dynamic library. That works perfectly on unix boxes and worked fairly well with older MinGW and older R (<=1.7.1). What I do in fact is that I specify -L$(R_HOME)/bin -lR when linking.

In Mac OS X native version: The R shell wrapper (bin/R) overrides default library search path with DYLD_LIBRARY_PATH and adds (among others) /usr/X11R6/lib. This causes problems when modules need (directly or indirectly) libraries from Apple's frameworks which are masked by X11. Examples for such packages are SJava and RGL. SJava needs JavaVM which in turn loads OpenGL framework. RGL

A while ago I compiled R 1.7.0 for AIX (with the above compiler - I'll call it xlc) and I was surprised that it went quite smoothly. Unfortunately with R 1.8.0 it's not as easy, but I succeeded at least partially. Static R works fine (after some tweaking), but --enable-R-shlib fails resp. produces a buggy R. Following are the problems I encountered (in a warning-to-fatal-error

Hi, i'm using Perl to control R under Windows via the Win32::OLE module and R's (D)COM server. This works fine, if i send commands and/or simple data structures to R. I am also able to get matrix-shaped return values into my Perl program, like this # snip ---------------------------------------------------- my $R = Win32::OLE->new('StatConnectorSrv.StatConnector');

R has spread far and wide with great success. It is not only used extensively in universities, but also apparently in governmental organisations and in industry. As the recent discussion of R's Pros and Cons shows, there are many reasons for this. It would be interesting to know just how widely R is used, where it is used most (and where least or not at all). Does anyone have a

I require some assistance with JGR, but following the mailing list link from http://jgr.markushelbig.org/FAQ.html leads me to http://mailman.rz.uni-augsburg.de/mailman/listinfo/stats-rosuda-devel which responds with No such list stats-rosuda-devel I was previously subscribed to this mailing list and want to resubscribe, but where has it gone? Many thanks, Oliver Mannion Programmer COMPASS -

I have been experimenting with interactive packages such iplots and playwith. Consider the following sample dataset: A B C D 1 5 5 9 3 2 8 4 1 7 3 0 7 2 2 6 Let's say I make a plot of variable A. I would like to be able to click on a data point (e.g. 3) and have a pop-up window tell me the corresponding value for variable D (e.g. 4). I am also trying to produce multiple

After the recent discussion about future direction of the Mac OS X port, I was toying with the idea to make R a proper Mac OS X framework. There are several advantages: OS X locates frameworks automatically, therefore any program wishing to link against R has only to specify "-framework R" at link time. Furthermore versioning is supported, i.e. if a program is linked against R 1.7.1

Some issues with the recent R-devel (rsync today) on Darwin: 1) Recent R-devel is a bit misleading concerning the R-framework installation: A new option --enable-R-framework was introduced, but install-Rframework ignores its absence (or --disable-R-framework for that matter) and tries to install the framework anyway in / which fails just after the R itself was copied into /Versions/.... I

Hello Tal, You asked *When is it helpful to use interactive plots? Either for data exploration (for ourselves) and data presentation (for a "client")?* My answer: It's helpful for checking data quality, for exploration with and without "clients", for checking results, and for data presenting. Notes: (1) It's difficult to explain interactive data visualization in

Dear R users / devs, There's been requests in the past for a text editor built into the Rgui for Windows, from which code can be submitted to the R console. Something along the lines of the script editor in S-Plus. Currently Rgui can only display a file read-only in a pager. As far as I can tell there's been little motivation to implement an editor, as most developers use (the

I need to implement some external callbacks to R and I'm not happy with the current REPL, since it prevents any general solution. Are there plans to improve the current REPL anytime soon? The current approach has some deficiencies you are surely aware of (only one input (=external event loop), the loop is blocked while waiting for input in R_ReadConsole, ...). But the major problem is

Dear Sirs, while > regexpr('(.{1,2})\\1', 'foo') [1] 2 attr(,"match.length") [1] 2 attr(,"useBytes") [1] TRUE yields the correct match, an incremented upper bound in > regexpr('(.{1,3})\\1', 'foo') [1] -1 attr(,"match.length") [1] -1 attr(,"useBytes") [1] TRUE incorrectly yields no match. R versions tested: 2.11.1

I want to use the R functionalities in my Java program. I found the Rserve that appear to suite my requirements but I'm facing some configuration problems. I' following the web page tutorial (http://stats.math.uni-augsburg.de/Rserve/doc.shtml) but I face the above problem: C:\Program Files\R\rw2010\bin>R CMD RSERVE Can't open perl script "C:\PROGRA~1\R\rw2010/bin/RSERVE":

Hello, I''m seeing problems with Xen and IRQ-sharing PCI cards which are passed through to a Xen DomU. As I''m not sure whether this is a problem with Xen or with the Debian Xen Kernel (2.6.26-13 from lenny) I''m using, I''d like to ask here before posting a bug. Reproducing the problem goes as follows: 1. Put a PCI card in the machine and make sure it shares

Just want to offer my congratulations to the JGR developers as the recepient of the 2005 Chambers Award. Great job, guys!! http://stats.math.uni-augsburg.de/JGR/ [Now, could JGR be updated to work with 2.1.0 (or be made R version independent, please... 8-)] Best, Andy

Hello. I'm writting a glx device and I've some performance problem with the eventloop registration system. The device is not refresh when there's no X event. That's problematic for animation and "smoothness" of display. Should I use threads or fork the R process to get and independant way to refresh my device ? Or do you know another way to refresh it ? Thanks

Hello, I can't find a package which calculates Kendall's tau-c. There is the package Kendall, but it only calcuates Kendall's tau-b. Here is the example from ttp://www2.chass.ncsu.edu/garson/pa765/assocordinal.htm. cityriots <- data.frame(citysize=c(1,1,2,2,3,3), riotsize=c(1,2,1,2,1,2), weight=c(4,2,2,3,0,4)) cityriots <- data.frame(lapply(cityriots,function(x)

Florian, I read already here and there that you shall not use shared interrupts in different PV DomUs, although I never found a written statement. But behaviour is exactly as you described, thus I took care that cards that share an IRQ are in the same DomU/Dom0. I also selected my motherboards accordingly. When I lately discussed lately with someone about MSI, I had the hope this could help,
