fcaR, Formal Concept Analysis with R

Formal concept analysis (FCA) is a solid mathematical framework to manage information based on logic and lattice theory. It defines two explicit representations of the knowledge present in dataset as concepts implications. This paper describes an R package called [fcaR](https://CRAN.R-project.org/package=fcaR) that implements FCA's core notions techniques. Additionally, it extension FCA fuzzy datasets simplification develop automated reasoning tools. first implement techniques R. Therefore, emphasis has been put defining classes methods could be reusable extensible by community. Furthermore, incorporates interface with [arules](https://CRAN.R-project.org/package=arules) package, probably most used regarding association rules, closely related FCA. Finally, we show application use design recommender system for diagnosis neurological pathologies.
