First preview of Incanter 2.0 (aka Incanter 1.9.0)

The first preview of the Incanter 2.0 is now available on Clojars as Incanter 1.9.0. This release mostly based on the work done during GSoC 2014 for project “Incanter and core.matrix integration” & includes following big changes (Please look to the wiki for full list of changes):

  • Incanter now uses only core.matrix functions with :vectorz as default implementations. You can use another implementation by adding corresponding dependency to your project file & selecting implementation using the set-current-implementation function;
  • Incanter’s dataset is now based on the Dataset from core.matrix that supports both labeled columns & rows. Dataset is also a matrix now, so matrix functions work on datasets as well;
  • Many functions are now deprecated in favor of corresponding functions from core.matrix (full list of deprecated functions is available on wiki).

Most of these changes are breaking the old API, so please look onto full list of changes that you can find in changelog.

Please, note that this version may have bugs, so please test your code with it & provide feedback. The next versions will provide more functionality from the list of tasks planned for Incanter 2.0, for example, reworking the read-dataset function, etc.

I want to say thank you to all people who participated in this release: Aleksandr Sorokoumov (aka Gerrrr) who did the major part of the work as part of the GSoC 2014; Mike Anderson (aka mikera) for great job on development of core.matrix, vectorz & many other projects & guidance during the GSoC; and all people in the Incanter mailing list who provided the ideas for new release & discussed the ways how to implement this.

Incanter 1.5.6 has been released

I just pushed the Incanter 1.5.6 to Clojars. This is bugfix-only release & includes many changes.

I’m planning to release the first preview of the Incanter 2.0 during the next few days – it will includes the changes made as part of GSoC, including the protocol-based dataset & tight integration with core.matrix.

Protocol-based dataset API in Incanter

As part of the GSoC for Incanter, Aleksandr Sorokoumov wrote the proposal for the new, protocol-based API for datasets that should be released as part of the Incanter 2.0.

If you’re using the Incanter, and if you’re interested, please join the discussion of the new API.

Planning breaking changes in the Incanter 2.0

As the GSoC is going forward, we’re also discussing the changes that will be made in the Incanter 2.0. One of the proposed changes – get rid of first/rest semantic for matrices. If you’re using them in your Incanter code, please answer to the list with your use cases…

Incanter 1.5.5 has been released

Incanter 1.5.5 has been released to clojars. This release contains the many bugfixes + some improvements that are documented in the change log. Please, take into account that there is one breaking change in handling of gamma distribution!

I want to thank all the people who contributed into this release!

Besides the 1.5.5 release we have some organizational changes that could help us to make Incanter’s development more active:

  • Incanter now has its own organizaion on Github, so please update your bookmarks. Now it’s easier to add new committers & we’re inviting all developers to
  • Incanter-related project was accepted for GSoC – this will allow to use core.matrix for matrix-related operations, and users can select preferred implementation.

After the 1.5.5 release we’re planning to concentrate our activity on the development of version 2.0 – including integration of core.matrix, implement the Dataset as protocol, etc. More information in this thread.

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!
