Thanks; I should have checked the bug list. Can I contribute a unit
test? I would think something like:
test(88.5, TESTDT[a=="d",list(MySum=sum(v)),by=list(b)],
data.table(b=INT(6,9), MySum=INT(7,11)))
would work. (That's based on just a few minutes of looking at the
sources, so I may have mangled something.)
Thanks,
Johann
