You might find the discussion at http://bit.ly/1ip1S2G (StackOverflow "proposing feature requests to the r core team") useful. For practical purposes, I would say R syntax *is* closed, because any changes to the syntax would have to (1) be implementable without unreasonable effort by the R Core members (ideally by extremely high-quality contributed code) (2) not break backward compatibility in any way, including the 7000ish packages currently on CRAN and 2000+ packages on BioConductor, which represent the tip of the iceberg of deployed R code ... As you say, multi-line comments and multi-line commands have been discussed many times, but most existing R users have already gotten used to the existing workarounds (e.g. using smart editors or an if (FALSE) { ... }) see also http://stackoverflow.com/questions/1231195/multiline-comment-workarounds Ben Bolker Ben Bolker ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
