"WitrynaOverview. The S4 system in R is a system for object oriented programing. Confusingly, R has support for at least 3 different systems for object oriented programming: S3, S4 and S5 (also known as reference classes). The S4 system is heavily used in Bioconductor, whereas it is very lightly used in “traditional” R and in packages from CRAN. " - Lm method r
