[R] JGR, Java and Kubuntu 7.04 ...

[John Logsdon]

R-ists

Yet again Java rears its ugly head.  

I have Kubuntu 7.04 running the Kubuntu-repository version of R 2.4.1-1.      
Yes it isn't the  very latest version but this is not the issue here.  

I want a Windows-like environment and everyone is talking about JGR.

I downloaded it and installed it along with rJava.  Both compile and install 
satisfactorily.

But when I come to run it:

> > library('JGR')
>
> Loading required package: rJava
> Error in dyn.load(x, as.logical(local), as.logical(now)) :
>         unable to load shared library
> '/usr/local/lib/R/site-library/rJava/libs/rJava.so':
> /usr/local/lib/R/site-library/rJava/libs/rJava.so: undefined symbol:
> JNI_GetCreatedJavaVMs Error: .onLoad failed in 'loadNamespace' for 'rJava'
> Error: package 'rJava' could not be loaded


When I first tried to run it without Java being installed, I got a message 
saying that JDK wasn't installed but mentioned 1.4.2.  The version of Java 
actually installed as the latest from the Ubuntu repository is Sun 1.5.0.11.  
I don't see the point in installing old versions of Java just for one 
application because the language, or at least the writing, should be 
backwards compatible.  

In all aspects I have seen Kubuntu is a very impressive in checking 
compatibility.  Unfortunately this is frequently not the case with Java.  I 
steer clear of Java as much as possible.  

Can anyone suggest what I should do?  Use Windows perhaps?  Run Windows in a 
kvm virtual machine just to run R?  Put my head in a bucket of cold water?  
Is there an alternative IDE?  Is there a later JGR somewhere that is not yet 
on CRAN?

TIA
