[R] rJava problem
Basically, I’m trying to install rJava on my windows XP machine. I think I have succeeded in doing so as it appears in the list when i type library() in R. However, when i type ‘library(rJava)’ I get an error dialog box saying: 'This application has failed to start because jvm.dll was not found. Re-installing the application may fix this problem' When I press 'OK' on the dialog box, I get the following in the R console: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library 'C:/PROGRA~1/R/R-25~1.0/library/rJava/libs/rJava.dll': LoadLibrary failure: The specified module could not be found. Error : .onLoad failed in 'loadNamespace' for 'rJava' Error: package/namespace load failed for 'rJava' Do you have any ideas how I can fix this? I really would appreciate any help you could give me? I am using java's jdk1.6.0_01 Thanks -- View this message in context: http://www.nabble.com/rJava-problem-tf3771205.html#a10661885 Sent from the R help mailing list archive at Nabble.com. __ R-help@stat.math.ethz.ch 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.

Re: [R] rJava problem
Ah thanks for that. That seems to have done the trick. But I'm not sure whether I have copied the right jvm.dll file into the path. I have 3: ~\Java\jre1.6.0_01\bin\client -this is the one i copied ~\Java\jdk1.6.0_01\jre\bin\client ~\Java\jdk1.6.0_01\jre\bin\server Did I copy the right one? or do the all have exactly the same file but just placed in different directories?

I have 3 places where a jvm.dll file can be found: ~\Java\jre1.6.0_01\bin\client -this is the one i copied ~\Java\jdk1.6.0_01\jre\bin\client ~\Java\jdk1.6.0_01\jre\bin\server Did I copy the right one? or do the all have exactly the same file but just placed in different directories? The first one works for me (from the JRE), since I don't have the Development Kit, only Runtime Environment. Try using comp from the system command prompt and compare files to see if they are same. -- View this message in context: http://www.nabble.com/rJava-problem-tf3771205.html#a10662482 Sent from the R help mailing list archive at Nabble.com. __ R-help@stat.math.ethz.ch 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.
Re: [R] rJava problem
Could someone please tell me where I can find a simple example, which does not require linux!, on how I can see if this is working and get me started using rJava. I have read the document 'Getting Started with the R-Java/Omegahat Interface' and have tried to type in things such as .JavaConstructor(JButton, A button) in the R console after loading library(rJava). However i keep getting the error: Error: could not find function .JavaConstructor Any help would be so greatly appreciated.

Re: [R] rJava problem
Ah ok, thanks. However (again!), when i try to strat the jvm using .jinit() I don't seem to be able to as I get the message: Error in .jinit() : Cannot create Java Virtual Machine What is going on here?
