Deedle v1.0 Release!

May 21, 2014 at 5:59 pm | Posted in csharp, fsharp, opensource, rstats | 4 Comments

Over the last six months, we have been quietly working away to complete the first official “1.0” release of Deedle, which we are delighted to announce today.  There are a lot of changes and new features in the 1.0 release, including:

  • Performance optimizations: e.g. when working with df.Columns, faster windowing & chunking, merging of series & frames, faster numerical per-frame operations & a few more.
  • New functionality: Stats module (see intro page)
  • Lots of assorted bug fixes
  • The API is not 100% backwards compatible, but is a lot more uniform and should be clearer.

The Deedle documentation has also improved a lot, in particular there is now good reference documentation for the Series, Frame and new Stats module.

Not to be out-done, the RProvider also gets an update today:

We are continuing to improve the RProvider, in particular developing support for interacting with remote and out-of-process R sessions.  We’ve also tagged a number of enhancements that are suitable for other enthusiastic souls to pick up and contibute.  See up-for-grabs.

Thanks to @tpetricek, @atomklein and @dcharbon (along with several others) for their work on these improvements!

Please enjoy.

  1. […] Deedle v1.0 is released! […]

  2. Great to see this reach version 1.0.

    When will Deedle get real time / streaming data support.

    • We don’t have concrete plans to implement real-time support, but we are definitely interested. If anyone wants to mock up some ideas we would be happy to review and discuss.

      • May be a mutable version to start with would suffice to start with. Next would be change propagation through composed calculation between the DFs.
