Re: [R] Aggregate with non-scalar function

Yes, that's exactly it! Many thanks, it all comes back to me now! It's the darn do.call that I can never remember somehow. I know I've reinvented this wheel several times -- you'd think I'd learn. Sigh. Again, my thanks! Regards, Mike On Nov 7, 2007 2:35 PM, jim holtman <[EMAIL PROTECTED]>

Re: [R] Aggregate with non-scalar function

Is this closer to what you would like? > x <- textConnection(" hostName user sys idle date time + 10142 fred 0.4 0.5 98.0 2007-11-01 02:02:18 + 16886 barney 0.5 0.2 94.6 2007-10-25 19:12:12 + 8795 fred 0.0 0.1 99.8 2007-10-30 05:08:22 + 5261 fred 0.1 0.2 99.7 20

[R] Aggregate with non-scalar function

R-Helpers, I'm sorry to have to ask this -- I've not used R very much in the last 8 or 10 months, and I've gotten rusty. I have the following (ff2 is a subset of a much, much larger dataset): > ff2 hostName user sys idle obsTime 10142 fred 0.4 0.5 98.0 2007-11-01 02:02:18
