Oh noooooes. install_gitub() is not what one should use when we have drat. I just rolled the Rcpp repo forward to 0.12.1.4, created a tarball and pushed it into the drat repo of the RcppCore organization. See the README here https://github.com/RcppCore/drat and just do drat:::add("RcppCore") install.packages("Rcpp") | works and the big matrix is allocated correctly. | | Thanks for the help and for the great work you are doing! Indeed. Nice to see this working.
