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
