TL;DR: update your library. It seems that you are using a package (lubridate) compiled against the most recent Rcpp release, but you are trying to load it using an old version of Rcpp. We try hard to smooth things out so that the transition "forward" (i.e., updating Rcpp) is as painless as possible. In fact, the recent v1.0.7 landed on CRAN with 2.3k+ reverse depends and only a couple of issues that got resolved with a rebuild. This is the inverse situation: the rest of the packages are updated (built against the newest Rcpp), but the local Rcpp version is an old one. This is not supported and cannot be supported; otherwise, our hands would be tied to make any progress or innovation. -- Iñaki Úcar _______________________________________________ Rcpp-devel mailing list Rcpp-devel@lists.r-forge.r-project.org https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
