Incanter 1.5.4 has been released

After several weeks since 1.5.2 release the new release of Incanter (with version number 1.5.4) has been deployed to Clojars.  This release contains several fixes & adds several new functions to incanter.core & incanter.charts.  See Changelog for more details.

P.S. 1.5.3 release was skipped because of an error that I made during deployment to Clojars. Don’t use it!

Incanter 1.5.2 (bugfix release)

I’ve just pushed the new release of Incanter to Clojars. This is mostly bugfix release that fixes several bugs, of different severity. There is also one enhancement – you can use logarithmic axes in charts. More information about fixed bugs and new functions is at changelog.

I want to thank all people who helped with new release by creating issues & sending pull requests!

Incanter 1.5.1: Bugfix release

The bugfix release of Incater was just pushed to Clojars.

It fixes 2 bugs – one nasty bug when functions called from transform-with were working on underlying data, modifying them, and 2nd – when 2-argument version solve thrown an error.

Incanter 1.5.0 has been released!

After long development, the new version of Incanter has been released to clojars. This version contains a lot of changes, including following:

  • For matrix operations the clatrix/jblas libraries are used – this should greatly improve performance (but you may need to install libgfortran3 package on Linux 64-bit. See jblas wiki for more information)
  • Interpolation functions were added to incanter-core module
  • You can save charts in SVG format by using the new incanter-svg module
  • The incanter-chart module was extended with support for scatter plots
  • Many bugfixes

Full list of changes could be found in changelog. There are 2 open issues that could affect your use of Incanter, please read about them in changelog. We’ll try to address them in the next release.

I want to say “Thank You!” to all people who provided new functionality, fixed the bugs, filed the issues, and participated in discussions in mailing list. Without you, this release simply didn’t happen!

The next steps in development will happen in direction of release 2.0, where the main change will be use of core.matrix library for all matrix operations.

Hammock Driven Development Cheat Sheet

This last weekend I re-watched Rich Hickey’s excellent (I would say awesome, but he would disapprove) clojure-conj talk on Hammock Driven Development, which I’ve summarized into this one page cheat sheet. The talk isn’t specific to Clojure, and the ideas can, and have, been applied to domains outside of programming. I recommend it for anybody working on solving novel problems in any domain.

An Illustrated guide to multi-core parallelism in Clojure

Here are my Clojure Conj slides, From Concurrency to Parallelism: an illustrated guide to multi-core parallelism in Clojure. The version of clojure.par I used isn’t publicly available yet, but I will be publishing it in my github repo ( soon, and hopefully it will make its way to master in the not too distant future.

I just want to thank everybody at the Conj for making it such a spectacular event! I’m already looking forward to next year.

Incanter executables

For a long time I’ve wanted a simple, double-clickable executable for Incanter, and now thanks to Alan Dipert’s swingrepl library I have it.

I have made an executable jar file, called incanter.jar, that launches a swingrepl, that includes Incanter and all of its dependencies, when double-clicked or started with the following command

java -jar incanter.jar

Note: Make sure to save incanter.jar with the .jar extension to ensure it executes correctly.

I have also used Apple’s Jar Bundler and SkoobySoft’s DMG Packager to create a Mac OS X executable that’s downloadable as a dmg file, Incanter.dmg.

Finally, I used Launch4j to create the Windows executable file,

To build incanter.jar from source, use script/package in the Incanter distribution on Github, or just use lein uberjar (lein will call the file incanter-standalone.jar, and will create a non-executable jar called incanter.jar).
