I think you are looking for ftable: xt <- xtabs(sales ~ company + year + quarter, data = DF) ftable(quarter ~ year + company, xt)
You also might want to look at the reshape package and the rpad package. Here is a demo of a pivot table in R using rpad for the user interface and reshape for the data manipulation that includes drag and drop: http://www.rpad.org/Rpad/DataExplorer.Rpad On Jan 22, 2008 8:19 PM, tom soyer <[EMAIL PROTECTED]> wrote: > Hi, > > I am trying to reproduce some functionalities of Excel pivot table in R, > sadly, I couldn't figure out how to do it.
