I can't comment on whether R can be extended in that way; that's R-core to answer. But @ is the slot extraction operator in S4 (see ?"@") so you'd need another operator symbol. But for faintly java-like annotation used for documentation and namespace management, you could look at the roxygen package; see https://cran.r-project.org/web/packages/roxygen2/vignettes/roxygen2.html S Ellison ******************************************************************* This email and any attachments are confidential.
