R GUI installation on Linux/SuSE 10.3
After a long sufferance I had succeeded in installing R GUI on my Linux/SuSE system. It worked fine. Unluckily a system upgrade patch messed up my monitor so I had to reinstall SuSE 10.3 and every other application on top of it. I have R running back with text interface. I tried to get the nice R GUI up & running again. I followed all the steps to reinstall the R GUI but this time I get a

ClassNotFoundException when running distributed job using rJava package
Hi, I have a MapReduce Java code, which I am calling from R using rJava. I have prepared the R package and tested that successfully. But when I deployed the package in a cluster and executed it, I am getting ClassNotFoundException. If I run the same job directly without integrating with R, it runs perfectly. Here is my R code: library(rJava) muMstSpark <- function(mesosMaster = NULL, input =

Bug#123084: r-base: R documentatio search engine unusable with Mozilla 6 (OK with netscape 4.7x) (PR#1202)
As there is nothing Debian-specific in this bug report (and the .deb of the JVW is not from Debian either), I am forwarding this to R-bugs. My recollection from recent discussions on the R mailing list is that currently /no/ browser other than Netscape supports the Java search engine -- is that correct or was there some Netscape derivative (galeon?) which does? Maybe the documentation should be

Unable to execute Java MapReduce (Hadoop) code from R using rJava
Hi All, I have written a Java MapReduce code that runs on Hadoop. My intention is to create an R package which will call the Java code and execute the job. Hence, I have written a similar R function. But when I call this function from R terminal, the Hadoop job is not running. Its just printing few lines of warning messages and does nothing further. Here is the execution scenario: *>

RJDBC and multiple classpaths
Corect me if this is not the right place to post this. I have a mdbdriver.jar (to access an MSAccess file) under Linux. I bought the license from http://www.csv-jdbc.com/ guys. The driver work fine when tested with DBVisualizer or another JDBC thing. The problem is that driver needs 3 other more jar files to work. Under R I have tried this and does not work: > library(RJDBC) Loading required

trouble loading JGR on Debian
Dear developers I am unable to (properly) load JGR on Debian testing. The JGR window will pop out and R will start up, but it will not perform any of the JGR specific library() calls (rJava, JavaGD, etc.) and will stuck at 100% CPU while the prompt will be non-responsive. The hack that helped previously in such cases, accessing Help > About [1], works no more. All R packages are installed via

R search applet initialization
R 1.5.1 is due to come out ... and I've just noticed that the R help.start page search applet doesn't work on my Mandrake 8.2 system even though I've upgraded mozilla to version 1.0 and I have a perfectly working java (all right, I'm using 1.4.0 now, but with mozilla 0.98 and java 1.3.1 it still didn't work). I had thought the problem due to a too-old mozilla version, but it

unable to source a .R file using RJava
I am unable to source a ".R" file using RJava. I tried a couple of different tests: 1) using java and the evaluation method core dumps 2) using ./RJava --example --gui-none to invoke source core dumps. 3) The line of R works if I go directly thru R and not RJava. Version info and code are below. Any help would be appreciated. --Laura O'Brien Applications

R.DLL mapping by P/Invoke
After a long processing, I was able to create a version of a small C# class that was able to emulate the rproxy by P/Invoke. This is mostly to find a workaround a performance problem of the StatConnector. It's almost work but ... I have strange memory exception when I call the print function. The variable seems to not survive from one call to the other. As there is no debug symbol for

Using R.dll in .NET IPC
Hi - I wrapped R.dll up using somebody code online (see below). I am comparing R on .NET IPC with R(D)COM. I got it all working. Except, I realize that in my client code of the IPC remoting, if I call 'plot' function in R via EvaluateNoReturn, I don't seem to see any results on the R plot window (although the window pops up). Is there anything to do with the code of R.dll wrapper

[LLVMdev] Improving cast<> failure messages.
Would anyone object to an attempt to improve cast<> error messages by outputting the expected type and the type received? The interface I'm thinking of is to use ADL to do visitor-style lookup, so we don't need to change every client. In particular, for clients in clang, we can just create these functions implicitly from our TableGen-generated files. I'm not sure about
