Does anybody happen to know if there's already a utility out there for dumping a sequence file of vectors to a csv file with vector,element,value?
I was hoping to shift some of my results over to R found a comment by Ted a while back suggesting that the easiest method is to spit out sparse csv triples and load them with sparseMatrix(x=c(1,1,1,1), i=c(1,2,3,3), j=c(1,1,2,1)) from the Matrix library. This wouldn't be that complicated to write, but I imagine I'm not the first person to look for it. If a utility like this doesn't already exist, does anybody think it would be a worthwhile enhancement to add an option onto the VectorDump utility to output to this format? If so I'd be happy to offer up a patch (although I might want to refactor the VectorHelper class to emit straight out to the writer -- I'm not too fond of generating huge strings)
