Actually I'm trying to load functions from .bc file and use them in the code that I'm building with IRBuilder. I found that function parameter type is %struct.reValue* and the type of the value that I'm passing to the function is {i32,i64}* But these types are quite equivalent, because of the definition: %struct.reValue = type { %"struct.reValue::$_44", %"struct.reValue::$_46" } %"struct.reValue::$_44" = type {...

...utility that allows multi-threaded data analysis using S+. We want to migrate it to R. However, the guy who preceded me here left some documentation indicating that he couldn't implement it because R didn't support threading. Also, he noted that the R-Java interface(org.omegahat.R.Java.REvaluator) wasn't thread safe even if R was. Can anybody who knows about this comment on it? I'd like to know if this is completed(his documentation claimed it was a work in progress?) Thanks a bunch, Nathan Whitehouse Programmer Shaw/Shaulsky Lab Baylor College of Medicine Hou...
