How to read R errors through JRI

+1 vote

I'm trying to communicate with my R using JRI though java. If i try to get the result of my R-Code as Double i get a NullPointer. Normally this is caused by an error of R. Is it possible to get the output of the R-Console into Java in order to read the error?

You'll be able to perform those R-Expressions, after the creation:

re.eval("log<-file('"+filepath+"')");
re.eval("sink(log, append=TRUE)");
re.eval("sink(log, append=TRUE, type='message')");

this codes writes every R-Output into the file specified by the String filepath.
