I have used it, but as a warning I'm not an expert user of R, Clojure, or Incanter. Incanter is very pleasant to use, because I personally much prefer coding in Clojure to R. The R language is powerful, but I don't find it obvious at all. You can also use Processing from Clojure if you need to roll your own charts, in addition to the very capable charting library that's already there to handle most routine visualization. That said, Incanter is immature compared to R. If Incanter does what you need, it might be a great fit, but R has a huge community and list of libraries right now. There's an R to Clojure bridge, but if you don't yet know R I'm not sure it's very helpful. Finally, Incanter is developing at a break-neck pace. Even if it doesn't do what you want today, it might tomorrow. Literally. I'd love to see the user base grow, because Clojure seems like a perfect fit for statistical computing.
