About 8 months ago, I blogged about http://www.dynamicalsoftware.com/analytics/oss http://www.dynamicalsoftware.com/analytics/oss using hadoop and R for open source data science. I found R to be very useful, especially if you want to graph large data sets. Since then, I have been playing with clojure with regards to data science. What I liked about clojure was that the programs looked more like transforming data sets with map, reduce, into, filter, merge-with, join, difference, union. You get more than just lists. You have maps, vectors, and sets too. The code looks like you are loading a lot of data into memory but with lazy sequences you are really processing these collections one element at a time. The so called threading macros (nothing to do with multi-threading) keeps the number of parenthesis down.
