I would dispute that there are not examples of large packages: certainly
some involve man-years of work. You will notice that pkg/R is normally
organized into files, each file containing a collection of related
functions. It doen't need to be like that: rpart for example is `one
function, one file' but built from a particular SCCS organization.
But unless the project is really large that seems a natural level of
granularity.
As Thomas has commented, a source package is a distribution model. That is
not how for masters of, e.g. the VR bundle are stored but rather generated
by a script. For personal use one can omit the INSTALL set and build a
binary package directly if more convenient.
