...p to 5-grams (sequence of 1 work up to 5 words) and I am searching for the frequency in my DF of the strings starting with a sequence of few words. I guess these days it is standard to use DF with millions of entries so I was wondering how people are doing that in the faster way.

Hi Fabien, I was going to send this last night, but I thought it was too simple. Runs in about one millisecond. df<-data.frame(freq=runif(1000), strings=apply(matrix(sample(LETTERS,10000,TRUE),ncol=10), 1,paste,collapse="")) match.ind<-grep("DF",df$strings) match.ind [1] 2 11...

...e with memory (crashing my Mac). I had to sub-divide the dataset to have it working correctly but I didn't manage to fully understand the issue. I am sure their is some other smart way to do that.

I noticed there are a lot of PHP based dynamic text replacement examples out there such as: http://artypapers.com/csshelppile/pcdtr/ Is there anything like this for Ruby / Rails? I know there''s always SiFR but that method is often frustrating because I''ve noticed significant slow down in page load time even on pages that use it sparingly.

...are my questions : 1) Has anyone ever tried to use such a big dataset? 2) Do you think that it would possible on a more powerfull machine, such as a cluster of computers? 3) Finaly, does R has some "memory limitation" or does it just depend on the machine I'm using? Best wishes Fabien Fivaz

...ading), but I'm not sure it's what I need. I have also read that speex *may* be encoded in Ogg container. Is it always the case? If so, I guess I shouldn't mind about speex and focus on Ogg. If anybody has an example for reading speex stream by frames, I would be thankful. Thank you, Fabien
