R-admin is fine.  The problem is in "Writing R extensions", which
would benefit from containing an explicit recipe for constructing an R
package, and in particular for constructing an R package under Windows
in both source and binary versions.  Several such recipes have been
posted to the internet or R-help.  The one that I have found to be the
most useful was posted to R-help by Gabor Grothendieck on 2 March 2005.
I am appending it below, with some trivial modifications of my own.
I think it would be very useful if this information were included in
the R-exts manual, perhaps at the end of the "Creating R packages"
section.

Making a package under Windows
------------------------------

Make sure that:

- you have read:
    "Writing R Extensions" manual
    http://www.murdoch-sutherland.com/Rtools/

- you have downloaded and installed the tools from
   http://www.murdoch-sutherland.com/Rtools/tools.zip.

- you have installed LaTeX (fptex or MiKTeX), perl, the Microsoft help
   compiler, and (if the package contains C or Fortran source code) the
   MinGW compilers, as described at 
http://www.murdoch-sutherland.com/Rtools/.
     (MiKTeX requires some additional setup, described at
   http://www.murdoch-sutherland.com/Rtools/miktex.html).

- your path contains the tools, htmlhelp, and the bin directories for R,
   LaTeX, Perl, and (if the package contains C or Fortran source code
   to be compiled with MinGW) MinGW.  The tools directory should be the
   first item in the path.

Assuming that the R installation is in \Program Files\R\rw....

1. Assuming your source package tree is in \Rpkgs\mypackage
    then at a Windows command prompt:

         cd \Rpkgs
         Rcmd install mypackage

    which will install it to \Program Files\R\rw....\library\mypackage.
    Or if you want to install it to a separate library:

         cd \Rpkgs
         md library
         Rcmd install -l library mypackage

2. Now in R:

         library(mypackage)
         ... test it out ...

    or if you installed it to a separate library:

         library(mypackage, lib.loc = "/Rpkgs/library")

3. Once it seems reasonably OK, see whether it passes Rcmd check:

         cd \Rpkgs
         Rcmd check mypackage

    and fix it up until it does.

4. Now create versions for Unix and Windows that you can distribute:

         cd \Rpkgs
         Rcmd build mypackage
         Rcmd build mypackage --binary
