Hi Doug, when using prepare_missing_cran_package the git repository is created with default branch name master and all tools we are using inside the r-pkg-team are relying on this. I tried to run routine-update on r-cran-sets which failed due to the default branch name debian/master. If you want to let team members upgrade this package flawlessly please stick to the branch name master. Kind regards Andreas. -- http://fam-tille.de
