What are the main differences in terms of software design, and tweaking it for your own needs. R6 vs S3. Which one is less fraigle?

This is a proof of concept demonstration for such implementation with S4 object-oriented classes, for meta-analysis of complex genomic data. Motivation In my previous post I reviewed the evolution of Bioconductor S4 classes for omics data. The most recent extended class is the...

If it is good enough for the Bioconductor community to keep develop and maintain, there must be something very usefull in it, for other disciplines to learn. Motivation Multi-omics data integration and...
