Dear R-devel, We are pleased to inform you that the R Consortium OOP Working Group has been making progress on the S7 (formerly named R7) package and are preparing to submit it to CRAN. The S7 package is a new OOP system designed to be a successor to S3 and S4.
As part of that effort, the group has identified a minimal set of narrow changes to base R that would allow S7 to exist as a CRAN package. The changes, in general, enable S7 to use R language features that are presently limited to only S4. The proposed patches: - make `@` an S3 generic. - make `%*%` an S3 generic. - enable double dispatch for S7. - enable `inherits()` to accept `S7_class` objects. The diffs for the individual patches can be found here: %*% - https://github.com/r-devel/r-svn/pull/105.diff inherits - https://github.com/r-devel/r-svn/pull/106.diff Ops - https://github.com/r-devel/r-svn/pull/107.diff @ - https://github.com/r-devel/r-svn/pull/108.diff The repository for the S7 package can be found here: https://github.com/RConsortium/OOP-WG Your feedback is important to us, and we would be grateful for your input on these patches. We aim to ensure that S7 is a high-quality package that benefits the R community, while being mindful of not disrupting existing projects or introducing breaking changes. If you have any concerns or objections, please let us know. Your insights and suggestions will be instrumental in shaping the final version of these patches, and we appreciate your help in this process. Thank you for your attention and contributions. Best regards, Tomasz On behalf of the R Consortium OOP Working Group ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
