I've been thinking pivot tables are a major innovation in the history of spreadsheet. I wondered if there is a natural way of pivot-tabling in more textual/literal environments like J.
I think I've found something. It's R's reshape. http://had.co.nz/reshape/ You may read the pdf paper that's linked on the page http://www.jstatsoft.org/v21/i12 R is a array-oriented programming language, hence a descendant of APL, which is mostly used in statistics domain. What do you think about reshape? How would J do pivot-tabling? Would it be similar to reshape or different?
