<< Larry: Aside from my question about the version, when you run it from the r> prompt, is it possible the query is so fast because you have done the query before and the answer is already in cache? One test is to exit RBase, come back in, define your variables and test again. If it truly is that fast the first time you do it, then I have no answer for you....
>> V 7.6. I've run each version several times in succession and the results (0.2 seconds vs 3.6 seconds) are very consistent. -- Larry
