[R] R GUI in Ubuntu?

[Andy Weller]

I should also add that:
library(JGR)

gives me the following output:
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

I have Sun's Java installed and thought rJava installed without problems...

Thanks, Andy
