Thank you all for the suggestions and alternate implementations. I ran
benchmarks on them all and wanted to share:
$ t2

NB. Thomas's suggestion
groups1 =: 3 : 0

Thanks for letting us know, Joe.
You might see a big improvement with unboxed symbols taken just before
comparisons as in:

c3 p1 0.2
c3 p2 0.35
c3 p3 0.45

Then you would run tc through REB's fine finder.

I also had noticed the change in representation of NA from __ to _. and removed
it from the test script. But I have no idea if this is affecting the Rserve
script itself nor how to modify it if so. And my code worked fine two weeks
ago, while the new representation of NA has been around for year
I don't see any recent changes in Rserve.
Can you give us a simple, reproducible example?
Try to isolate the problem to a few lines of J entered in a fresh session.
