Re: [R] rJava software
Hello, it seems that rJava tries to detect the path to the Java Virtual Maschine from a registry key which is not installed. I gues that the HLM means HKEY_LOCAL_MASCHINE where you find normally the path to your installed Java. On my Windows System i have for example the path HKEY_LOCAL_MASCHINE\Software\JavaSoft\Java Runtime Environment\1.6.0_24 where you can find the key for the Java installation path. Try to open regedit fromyour Windows console and convince yourself that the path is not present. Maybee a reinstallation of the JRE or JDK helps (for the registry key). Or try to put your Java installation (the location) on the OS system path (open the Windows Shell and type Java -version if a installation is already on the system path), maybee that helps, too. Also, does it matter where java is installed? Yes, it does matter because the OS has to find the executables and native libs of the JRE and rJava has to find them, too because it relies on them. I hope this helps. -- View this message in context: http://r.789695.n4.nabble.com/rJava-software-tp3383366p3383977.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

[R] New version of ecological modelling software available with improved R interface
Dear R users, again with the hope that this application can also be useful for some R users, i like to announce a new Windows version of the ecological modeling software Bio7. For information: Bio7 uses a pure Rserve approach to interface Java and R and has a feature rich GUI to access and execute R methods from Java embedded in a Rich Client Platform based on Eclipse. In this release (1.4) a new R perspective is available with a spreadsheet component and the R-Shell view to import, export data from Excel, OpenOffice and CSV and to transfer them to a R workspace. In addition new methods have been added to the R-Shell interface to transfer data from and to the spreadsheet component. http://www.uni-bielefeld.de/biologie/Oekosystembiologie/bio7app/flashtut/rperspective.htm http://www.uni-bielefeld.de/biologie/Oekosystembiologie/bio7app/flashtut/rperspective.htm Furthermore Bio7 1.4 embeds several tools for: - Creation and analysis of spatial explicit simulation models. - Image Analysis (embedded ImageJ). Transfer of images to and from R is supported!

Re: [R] R running as a server on windows?
Yes you can run the Rserve application on a remote computer in e.g network and then you can connect it from your Desktop computer. I've done this already with a remote Linux computer (Rserve is running very stable on a Linux computer). For example i clustered an R,G,B image on a linux computer with R to make use of the additional RAM without to load my Desktop application (The remote connection will be a new feature in the next release of my application). If the mentioned application uses Rserve and can be configured with an ip adress etc. it should be easily possible. Please read the information how to config Rserve(and read the security info carefully!) on the Rserve website: http://www.rforge.net/Rserve/ http://www.rforge.net/Rserve/ -Documentation I hope this information helps!

[R] A cluster package question and request for images
Dear R developers, i'm developing a Java application with a very efficient image transfer api between ImageJ and R. In my next release i can transfer bytes to R very fast with the help of the Rserve application. Furthermore i added an easy to use interface to the clustering algorithm clara in the cluster package. At the moment i can cluster an R,G,B image with size 4000*4000 without any problem on a 32-bit package (with 3GB ram) with a good speed . For the clustering i have to convert the byte vectors to integer vectors and add them to a matrix. My question is if it is possible to change the package in that way that the function clara which i use for clustering also accepts smaller datatypes so that i can cluster bigger images (or more dimensions) without running out of memory. In addition is there a better way to transfer the vectors to this function maybe without the need to bind the vectors to a matrix (which costs little bit more time)? Any answers or comments are appreciated.

Re: [R] PCA on image data
Dear Jorge, As i've already written the princomp method works for me.

The background is that i've an application which can transfer images to R and create images from R very fast (using ImageJ and RServe). I've already clustered successfully image data with the cluster package. If i now have more than three channels (or bands - R,G,B) i want to reduce the dataset with the PCA. So which data (as a matrix) represents the first pc or how can i calculate from the results this matrix?

Re: [R] Calling R function from Java
Hello, I've created an application (IDE for ecological modelling) on the basis of Eclipse which uses Rserve http://www.rforge.net/Rserve/ http://www.rforge.net/Rserve/ to archieve this. I also implemented a small api to send or access data from or to R and Java. The transfer is very fast. I've also created a lot of examples which demonstrates the use. If this sound interesting for you visit http://www.uni-bielefeld.de/biologie/Oekosystembiologie/bio7app/ http://www.uni-bielefeld.de/biologie/Oekosystembiologie/bio7app/ for more information. The application is OpenSource and free to use.

Re: [R] Building packages including Java files
