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. --Laura O'Brien Applications
