Deedle Build Status Build Status


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.


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:

All fsprojects and fslaborg projects have @fsprojectsgit as a backup maintainer who can help recruit new maintainers should things go cold.
