co-maintainers welcome lssndrbarbieri@gmail.com Alessandro Barbieri Creates classes with reference semantics, similar to R's built-in reference classes. Compared to reference classes, R6 classes are simpler and lighter-weight, and they are not built on S4 classes so they do not require the methods package. These classes allow public and private members, and they support inheritance, even when the classes are defined in different packages. https://github.com/r-lib/R6/issues https://cran.r-project.org/web//packages/R6/R6.pdf https://cran.r-project.org/web//packages/R6/news/news.html Winston Chang winston@stdout.org r-lib/R6
