Implementing Data Frames in OCaml

I have been learning OCaml on my own and I've been really impressed with the language. I wanted to develop a small machine learning library for practice but I've been presented with a problem.

In Python one can use Pandas to load data files then pass it to a library like Scikit-Learn very easily. I would like to emulate the same process in OCaml. However, there doesn't seem to be any data frames library in OCaml. I've checked 'ocaml-csv' but it doesn't really seem to be doing what I want. I also looked into 'Frames' from Haskell but it uses TemplateHaskell but I believe a simpler way to do the same thing should be possible if Pandas can simply load the data file into memory without compile-time metaprogramming. Does anyone know how data frames are implemented in Pandas or R, a quick search on Google doesn't seem to return useful links.

Is it possible to use a parser generator such as Menhir to parse CSV files? Also, I'm unsure how static typing works with data frames.

Would you have a reference about the format of data frames? It may not be so hard to add to ocaml-csv if CSV is the underlying representation. The better is to open an issue with a request and the needed information.
