From I've updated Java there are a lot of problems with R...
I think the most annoying error is when I want to import to or export from R some xlsx files. Usually these kind of error is occured:
Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl, :
java.lang.OutOfMemoryError: GC overhead limit exceeded
Before I uptaded Java the same xlsx files were imported and exported without problems.. What can I do in this situation?
