Welcome.
I've been using roxygen2 for a few months, not an expert.
I think you are missing the fact that your need a DESCRIPTION file
separate from the R code. Basically, you need all of the stuff for
building an r package, just not a separate man folder because
roxygenize will make those things.
In my case, I have never tried to do the package build from inside R
itself, but I do like you where I start R in the folder "above" the
package, say "rockchalk" is my package, I do
> roxygenize("rockchalk")
That builds the documentation files and futzes with the DESCRIPTION
and NAMESPACE.
After that I just exit R and run "R CMD build" and "R CMD check
rockchalk_1.xx.xx.tar.gz".
Here's how I got started with this. Get a package you like. Test that
out. My favorite lately is "lmtest". In R you can run
"download.packages("lmtest", dest="/tmp")" to grab the source. First
check you can rebuild the package following the manual in R
extensions. Then you can experiment putting in roxygen markup to see
if you can still build the package. There's a fabulous tool in the
Rd2Roxygen package. That's an awesome tool in my experience, it will
scan an existing package and convert the R program files to roxygen2.
It is the most amazing thing I've seen in quite a while.
