Hello R-helpers. I've tried to recreate a parallel version of tapply() and table() using a combination of the parallel functions mclapply() and pvec() and papply(), but haven't been successful. In the end, I'm trying to get a cross tab of two vectors. I currently (can) use tapply(..., sum) and table(), and even xtabs() and ftable(), but with tens of millions of words and tens of thousands of files to loop over, it take a long time, like days.
Does anyone know of a parallel version of tapply(), table(), xtabs(), or ftable()? Or has anyone created something that approximates a parallel version of one of these functions? Thank you for your time and help. Earl Brown ----- Earl K.
