The right place to ask is the package-dev mailing list. It is possible to list dependencies and then users can specify dependencies=TRUE in their call to install.packages. I also know that there have been super-packages that do install multiple other packages. When you issue the command `library(tidyverse)` you get a boatload of packages loaded at once, so why not look at that example. It has R code in several modules.  The other mechanism I've seen is to construct a github page that has the needed code.

Rhelp is also a plain text mailing list.
