The devtools package makes it all lot less painful, so start by installing that. https://cran.r-project.org/web/packages/devtools/README.html <https://cran.r-project.org/web/packages/devtools/README.html>
ESS has a minor mode ess-r-package-mode that will drive devtools commands, for instance ess-r-devtools-load-package (C-c C-w C-l) will recompile and reload all the code in your package while working around locked namespaces. (in an R buffer in a package source directory) M-x ess-r-package-mode C-c C-w C-l When activated in a R buffer, ess-r-package-mode makes it so that evaluating definitions in that a buffer goes into the package namespace (I usually just C-(c-w-l) so I’m not super clear on what’s going on there ) Peter > On Mar 7, 2018, at 17:28, Boylan, Ross <ross.boy...@ucsf.edu> wrote: > > Can anyone suggest to me a good way to develop R packages with ESS?
