ocaml-dataframe

Simple and (reasonably) type-safe dataframe api implemented in pure ocaml

This is mostly a work in progress to experiment with how to use the ocaml type system to provide more type safety to dataframes. It aims at providing the following functionalites:

• Cover some basic types for columns, int, float, string, ....
• Provide the possibility for the user to add new element types (e.g. for date, time), as well as new storage types (e.g. packed int options, ...).
• Functional api with immutable dataframes.
• Use applicative for filtering dataframes and for map like operations.
• Read/write from csv with automated type detection.
• Maybe support join ? (TODO)
