Hi all, We're using Rserve and RandomForest to do classification from within a Java program. The total is about 4 lines of R code: library('randomForest') x y future fit<-randomForest(x,y,no.action=na.roughfix,importance=T,proximity=T) p<-predict(fit, future) What is very frustrating is that we have tried this two different ways (both work in R): 1. Load x, y, and future

Hi, I want to run the R-function ctree (package party) from Java over Rserve with the following Java-Code: try{ RConnection v = new RConnection(); v.voidEval("library(party)"); v.voidEval("try(load(\"C:\\Documents and Settings\\daten2.rda\"))"); v.voidEval("try(pdf(\"C:\\Documents and Settings\\test4.pdf\"))"); v.voidEval("plot

I have problem to have fonts in graphics using GDD. R version: R 2.2.1 (2005-12-20). GDD version: GDD_0.1-8.tar.gz Platform: Linux 2.6.17-gentoo-r8 #2 SMP Sat Nov 4 21:16:47 EST 2006 i686 Intel(R) Pentium(R) 4 CPU 3.00GHz GenuineIntel GNU/Linux I have configured the basefont.mapping file accordingly to the path of the font on my computer: base.norm:/usr/share/fonts/corefonts/arial.ttf

Hi Apologies for this question. I have read the help for GDD and font mapping, and it tells me that the config file, /usr/lib/R/library/GDD/fonts/basefont.mapping is responsible for mapping fonts to the GDD library. However: > .GDD.font() [1] "/usr/X11R6/lib/X11/fonts/Type1/l048013t.afm" [2] "/usr/X11R6/lib/X11/fonts/Type1/l048016t.afm" [3]

hi I'm using the GDD package (in a 64bits fedora machine using R 2.3.0) to save in a png file some plots and i noticed that changing the lwd parameter does not change my line width I tried the same script in a Windows based R (2.2.1 r36812), using no GDD, and it worked. Does anybody has a clue? My testing script is something dumb like this: library(GDD) GDD("pres24.png",

Hi I was searching for some X replacement for my job in R and i found the GDD I installed it and I match all the system requirements. My problem (maybe a dumb one) is that every plot comes with no font and i cant find a simgle example of a plot WITH FONT DETAIL in the list can anybody help me? a simple example: library(GDD) GDD("something.png", type="png", width = 700,

I succeeded in compiling and installing the GDD package under my FreeBSD 6.1 box after eliminating ifdef DEBUG ? ?PKG_CFLAGS+=-DJGD_DEBUG endif in Makevars.in Now, with the following code .............................................. grafico1<- function() { plot(1:length(tabella[,1]),tabella[,2],ylim=c(Ymin,Ymax),type="h",

I'm trying to get Cairo and RApache to work together on OS X leopard. Initializing Cairo stops the whole HTTP response. Apache logs show this message: Break on __THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__ () to debug.

The Rserve documentation at http://rosuda.org/Rserve/doc.shtml#start states that even when making multiple connections to the Rserve, Windows won't separate workspaces physically and share environments, which will obviously cause problems and should therefore not be used. Are there any alternatives for the windows platform? Ralf

Hi all I was trying to isntall RApache last week but ran into strnge problems that no one else seems to be experiencing. At least I couldn't find anything after extensive googling. First off, the machine I'm installing on looks like this: Dell Optiplex 745 32 bit 2GB RAM Fedora 15 httpd -v Server version: Apache/2.2.21 (Unix) Server built: Sep 13 2011 13:46:23 R: R-2.14.0-3.fc15.i686

I am trying to create a .jpg file with multiple graphs on it. I am creating this file through a java servlet which connects to R using RServe. In the code below, col is an int array which has a list of the col numbers of the data file whose data i have to use for plotting. c=new Rconnection();

Hi, this is Charlie and I am trying to embed R in my apache server. However, I am having problem with installation. The R projet says that we can install add-on package with command $R CMD (rapache.0.1.4.tar.gz). However, I try to use it in command windows (windows xp) and an error shows. Please tell me when I can use the command (in c?? or in the same folder with the file). thx. [[alternative

Hi all; Now I'm developing web application by using rapache in ubuntu. My problem is that as users execute the application, the server PC cumulates memory. After users close or refresh the application page, the server PC memory is still cumulated. Now I'm renewing apache machine by manually in terminal. Is there any way to kill memory when users refresh or close the application page?

Has anyone had problems with Rapache that don't show up on command line execution of R? I just ran into this loading rgdal in Rapache page and having a problem with loading shared object. The final complaint was that Stop_XMLParser was undefined- this was surprising since grep -l showed it in expat lib and it worked fine from command line. Finally, I noted the search path had apache/lib ahead

Executive summary: getRemotePkgDepends seems to use the wrong default string to (try to) download the CRAN package information. ======================== Someone asked me about the behavior of tools::pkgDepends() , and in investigating I discovered the following: ## tools:::getRemotePkgDepends ## undebug(tools:::getRemotePkgDepends) tools::pkgDepends("GDD") ## Error in

Hello all, I searched on the www but could not find installation instructution for rapache on windows. The page says that the release runs on UNIX/Linux and Mac OS X operating systems. Has anyone been able to configure it on windows? Any idea how to go about it? Thank you.

Hi all, I need your opinion about using R-Rapache to build a knowlegde base to bioinformatics field. I have copious amount of genotype information (some few million records) and would like to store it in MySQL database. Then, using RMySQL connector I would like to use it for further analysis using R over a web interface. The web interface which I am thnking off, just does not serve the purose of

I installed mod_r according to the specifications, and have been trying to get the demo script to work correctly. I am running debian, the latest build of R, apache 2 with prefork mpm, and the latest mod_r. Is anyone else using this module successfully? I added: LoadModule R_module mod_R.so <Location /test/hello> SetHandler r-handler Rsource /var/www/html/test.R RreqHandler

Hello, I want to import R-output via Rserve to Java, especially for the function ctree from the package party. Rserve is working properly. Yet, I only get the predictions with the Java code try{ RConnection c = new RConnection(); ... c.voidEval("modell <- ctree(...)"); REXP y = c.eval("nodes(modell,1)[[1]]$prediction"); ...
