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)
