Thank you Jeff. Your idea, as i mentioned on my previous posting, did
indeed work. I read somewhere that both data table dplyr do great many
things and i plan to learn both as much as i can. Suggestions on this list
either get you the answer you are looking for or give you lead to an answer.
Thank

It is probably preferable to obtain logical vectors for Num and Day before
starting tabulation.

You seem to be unaware of the "aggregate" data processing concept. There are
many ways to accomplish aggregation, but I am not fluent in data.table methods
but knowing the concept is the first step.
Perhaps look closely at [1], or Google for data table aggregation yourself?

Thank you both Boris and Jim. Thank you, Boris, for advising to read the
posting guide; I had and I just did.
Jim’s idea is exactly what I want; however, I could not pass sset1, sset2,
etc. to the j nested loop and collect the results in an vector.
Here attached my code, file, and my question whi
Hi Ek,
I think you want your example to look like this:
Sample<-read.table(text=
"Num Color Grade Value Month Day
1 yellow A 20 May 1
2 green B 25 June 2
3 green A 10 April 3
4 black A 17 August 3
5 red C 5 December 5
6 orange D 0 January 13
7 orange E 12 January 5
8 orange F 11 February 8
9 orang
There's a lot that doesn't make sense here. I think what you need to do is
produce a small, reproducible example, post that with dput() and state your
question more clearly - including what you have tried and what didn't work.
You'll probably be amazed how quickly you will get good advice if
