...e the output of the analysis in a dataset for further
manipulation. I have a data set with vote totals, with one column being the
office name being voted on, and the other being the party of the candidate.
My votes are in the column "vc.n". I did the analysis I want with:
work <- by(sd62[,"vc.n"], sd62[,c("office.nm","party.abbr")], sum)
the str() output of work looks like:
> str(work)
'by' int [1:9, 1:11] NA 30 NA NA 0 0 0 NA 33 25678 ...
- attr(*, "dimnames")=List of 2
..$ office.nm : chr [1:9] "ATTORNEY GENERAL"...
