Lichess.org already offers a nice collection of analysis tools players can use to understand their performance.
This repository provides the basic tools to perform your own research on chess games data with the limitless potential of R.
count_material.R includes a customizable material_score() for FEN positions.
Version 1.0.2 adds example content for processing positions with Stockfish and saving the evaluations for all positions of games in long format.
See evaluate_games.R and its dependencies. This engine analysis content works properly, but I intend to improve it further.
The most advanced feature of this repo is the fen_move function, which gets the
next FEN position in chess, given the current FEN position and the algebraic
move. Thus, allowing you to recreate every position in the game and save them in tibbles.

fen_move supports a number of variants, namely,
Standard (Including From Position)
Crazyhouse
Chess960
Three-check
King of the Hill
Horde
I plan to add support for some other variants in the future. Atomic, Duck, and Anti-Chess are the most likely to be added.
