unable to source a .R file using RJava
I am unable to source a ".R" file using RJava. I tried a couple of different tests:
1) using java and the evaluation method core dumps
2) using ./RJava --example --gui-none to invoke source core dumps.
3) The line of R works if I go directly thru R and not RJava.
Version info and code are below. Any help would be appreciated.

you could point me to the correct place to find a solution, I would much
appreciate it. I am new to the R community and not sure where is the

SJava embedded in R
Hi,
Here's some suggestions for troubleshooting the
install.
The CLASSPATH needs to be

$SJAVA_HOME/org/omegahat/Jars/antlr.jar
$SJAVA_HOME/org/omegahat/Jars/jas.jar
$SJAVA_HOME.
This allows the java compiler/interpreter to find

deleting symlinks only
hello list,
is it possible to delete a symlinked directory over a samba-share, without deleting
it's content but leaving the link-target as it is and deleting the
symlink only? If I interpret samba's behaviour correctly, on deletion samba does not
recognize the link as a link but as a directory, descends into it and deletes the
content recursively, finally tries to delete the directory
