I read through the "Writing R Extensions" document and am able to now create my own packages/libraries which so far are just well documented collections of my own R functions. I use package.skeleton() and the tools package to build these packages. However, it is not clear to me how to modify and update a package after its initial creation. How do you elegantly update e.g. the old help file when one added an argument to a function ? How do you keep most of the existing package structure when implementing incremental changes ?
In detail, Tobias is right. In summary: incremental changes must be made by manual updating the files. When I did it the first time, I had no latex background and it reminded me of r(un)off times. After you did it once, it's not that complex though, so bite the bullet.
Also check out the roxygen package, which allows you to build the documentation from comments in your source files. This makes documentation much easier to keep up-to-date, as it's right next to the code that you're changing. It also takes care of some of the tediousness of Rdoc by copying across the usage etc directly from the function definition. Hadley
