[R] littler and rJava

[John Laing]

Hello list,

I'm having some difficulty getting rJava to load in littler. Even
after a R CMD javareconf and a reinstall of littler, I get this:
jlaing at xenon:~$ r -e "require(rJava)"
Loading required package: rJava
Loading required package: methods
Error : .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object
'/usr/local/lib/R/site-library/rJava/libs/rJava.so':
  libjvm.so: cannot open shared object file: No such file or directory

It works fine with Rscript:
jlaing at xenon:~$ Rscript -e "require(rJava)"
Loading required package: rJava
Loading required package: methods

Presumably my load paths are misconfigured, but I can't figure out where:
jlaing at xenon:~$ R CMD javareconf
