I was hoping for something that really was that simple but I tried and so far it seems that I also must also

  1. when I run skeleton.package realize that I must use the arg path = "library" The example that is shown there appears to omit that.
  2. download and install tools.zip, perl and windows help as listed at:

   http://www.murdoch-sutherland.com/Rtools/

I got tripped up for quite a while when it could not find hhc.exe and I finally realized I had not downloaded the windows help distribution.

3. change the name of the package in the DESCRIPTION file -- it seems that the name = arg on package.skeleton did not change it for me.

4. make changes to the documentation files. I am just working on this now. Some default null documentation exists but it appears that it MUST be modified in order to get a working package so this makes another step.

There maybe other things but its taken me several hours just to get this far and I do not yet have a functioning package.

I think it would be handy if everything you need to know to actually create a minimal functioning package were in ?skeleton.package so that one could create a minimal functioning package without actually reading the extensions manual and then incrementally improve it. Right now there is quite a bit you have to know just to get to that point.

I have so far looked at skeleton.package, readme.packages in rw1091, murdoch-suthertherland.com link mentioned above and the extensions manual so the startup to doing this is really a multi-step complex process.

The skeleton.package idea actually seems quite nifty but I think it needs more work before one can really claim that its a one-step process to create the example package.
