Re: [R] Data aggregation question

Hi all, table() did the trick, and very efficiently, too! Thanks for the advice, Dave On Thu, Jul 28, 2011 at 5:39 PM, David Winsemius wrote: > > On Jul 28, 2011, at 4:24 PM, David Warren wrote: > > Hi all, >> >>I'm working with a sizable dataset that I'd like to summarize, but I >>

Re: [R] Data aggregation question

You don't offer a reproducible example, but what do you need that table() doesn't provide? testdata <- data.frame(A=factor(sample(1:3, 20)), B=factor(sample(1:3, 20)), C=factor(sample(1:3, 20))) table(testdata) Sarah On Thu, Jul 28, 2011 at 4:24 PM, David Warren wrote: > Hi all, > >     I'm wor
