Why link to github rather than the project webpage?

http://incanter.org/

The GitHub page is currently a much better introduction to Incanter than the web page.

Also most HNers are familiar with GitHub and since Incanter makes good use of its features, it would be hard to make incanter.org a better resource for people just getting started.

This might have been a better page to choose then: https://github.com/liebke/incanter/wiki#getstarted

I get a bit put-off when the first thing I see on a project website is a source tree, unless that's what I was expecting.

They use GitHub to the max so I'm guessing they actually like GitHub. I've heard people who like GitHub complain about other code hosting sites not having a source tree on the project website. Never heard an avid GitHubber complain about the source tree on the project website. So I'm guessing that it suits their aesthetic just fine.

Looks like they've got a pretty healthy base library set up, but I'd be curious if anyone's seen a thorough comparison of R and Incanter. Googling isn't much help.

There is also RIncanter (https://github.com/jolby/rincanter). From project's page: "Rincanter is a Clojure and Incanter wrapper around the Rosuda JRIEngine Java/R bridge. The hope is to allow easy access to an embedded R engine from Incanter. It also offers translation between Clojure and Incanter datatypes and R datatypes such as R dataframe to Incanter dataset."

Is there anyone who is using Incanter in a production environment as yet?

I believe that the Flight caster guys were using it, yes. It's one of the more mature libraries in the Clojure ecosystem.

Speaking of which, whatever happened to the Infer library those guys released? Seems to have disappeared off github.

Looks quite interesting. Is there any way to export incanter charts as TikZ based figures to include them in LateX documents?

currently there is no such support in Incanter. Chars are implemented via JFreeChart that can export to JPEG & PNG out of box, although it's possible to export charts to other formats, such as PDF and Incanter supports it out of box with incanter.pdf/save-pdf function (http://data-sorcery.org/2010/02/05/pdf-charts/)
