I assume that's the Rcpp::S4 class? I've seen it mentioned various places (e.g. the Rcpp-introduction vignette) but I can't seem to find a list of its methods & API. begin() is a method I'd never heard of, I assume it returns a pointer to the first element of the vector? -- Ken Williams Senior Research Scientist Thomson Reuters Phone: 651-848-7712 [email protected] http://labs.thomsonreuters.com _______________________________________________ Rcpp-devel mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
