Deedle

<img align="right" src="https://github.com/fslaborg/Deedle/raw/master/misc/logo.png" alt="Deedle" />

Deedle is an easy to use library for data and time series manipulation and for scientific programming. It supports working with structured data frames, ordered and unordered data, as well as time series. Deedle is designed to work well for exploratory programming using F# and C# interactive console, but can be also used in efficient compiled .NET code.

The library implements a wide range of operations for data manipulation including advanced indexing and slicing, joining and aligning data, handling of missing values, grouping and aggregation, statistics and more.

Build

Install .NET SDK 9.0 or higher, then run:

dotnet tool restore
dotnet paket restore
./build.sh        # Linux/Mac
.\build.ps1       # Windows

Documentation

More information can be found in the documentation.

  • Quick start tutorial shows how to use the most important features of Deedle. Start here for a 10 minute intro!
  • Data frame features provides more examples of using data frames including slicing, joining, grouping and aggregation.
  • Time series features discusses data and time-series manipulation, such as sliding windows, sampling and statistics.
  • Using Deedle from C# shows the idiomatic C# API for working with Deedle.

Automatically generated documentation for all types, modules and functions in the library is available in the API Reference:

More functions related to linear algebra, statistical analysis and financial analysis can be found in Deedle.Math extension. Deedle.Math has dependency on MathNet.Numerics.

  • LinearAlgebra module provides linear algebra functions on frame.
  • Matrix module provides matrix multiplication between frame, series, matrix and vector. They are also available via type extensions.
  • Stats module provides extra statistical functions on frame and series by applying existing functions in MathNet.Numerics.
  • Finance module provides statistical functions specific to finance domain.

Package Downloads
NBi.Framework.Tools

This package contains the NBi framework and references each dll to your project. This package is not intended to be directly used by end-users willing to create test-suites. Check the package NBi.VisualStudio, if you want to facilitate the usage of NBi from Visual Studio. NBi is a testing framework (add-on to NUnit) for Business Intelligence and Data Quality. It supports the Microsoft Data platform (SQL Server Database engine, SSIS, SSAS, SSRS) but also MySQL, PostgreSQL and other NoSQL solutions.
FsLab

FsLab is a combination package that supports doing data science with F#. FsLab includes literate scripting converted to HTML and PDF, and by default references Deedle (a data frame library), FSharp.Data (for data access) and XPlot (for visualization). You can optionally add any other nuget packages.
Deedle.Math

Deedle implements an efficient and robust frame and series data structures for manipulating with structured data. It supports handling of missing values, aggregations, grouping, joining, statistical functions and more. For frames and series with ordered indices (such as time series), automatic alignment is also available. This package installs the core Deedle package, Deedle.Math extension and Mathnet.Numerics to extend mathematic functions on Deedle Frames and Series.
Deedle.RPlugin

Deedle implements an efficient and robust frame and series data structures for manipulating with structured data. It supports handling of missing values, aggregations, grouping, joining, statistical functions and more. For frames and series with ordered indices (such as time series), automatic alignment is also available. This package installs core Deedle package, together with an R type provider plugin which makes it possible to pass data frames and time series between R and Deedle

Seddryck/NBi
NBi is a testing framework (add-on to NUnit) for Business Intelligence and Data Access. The main goal of this framework is to let users create tests with a declarative approach based on an Xml syntax. By the means of NBi, you don't need to develop C# or Java code to specify your tests! Either, you don't need Visual Studio or Eclipse to compile your test suite. Just create an Xml file and let the framework interpret it and play your tests. The framework is designed as an add-on of NUnit but with the possibility to port it easily to other testing frameworks.
