[R] Package structure question (resolution)

Thanks to Max Kuhn, Jeff Laake, Duncan Murdoch, and Dirk Eddelbuettel, for their tips that eventually helped me get my teeth around this one.

I'm in the process of documenting my experience, in case others find it useful. Please email me if you want to add to this or clarify anything.

However, to close this thread, in a nutshell, working in Linux:

  1. package.skeleton().
  2. Make obvious changes to files.
  3. R CMD check packagename.
  4. R CMD build --binary packagename.
  5. The result of 4 should be a working Linux package, .tar.gz.
  6. Unpack the .tar.gz file by hand, and zip the resulting directory.
  7. The result of 6 should be a working Windows package, .zip.

If there is an easier way to get both the Linux and Windows packages (without installing any extra specialized tools), I'd be interested.

Problems encountered:

  1. The --binary option seems necessary now, but perhaps it wasn't in earlier versions? Not sure. This may have resulted in my quick success in Linux (where we are running an older version of R), but problems in Windows (newer version).
  2. In the process of making early mistakes, my Windows installation was corrupted by some odd folders in R/library that generated the following error message:

> utils:::menuInstallLocal()

updating HTML package descriptions
Warning message:
no package 'file678418be' was found in: packageDescription(i, lib.loc = lib, field = "Title", encoding = "UTF-8")

I'm hesitant to call this a bug (because there might be a good reason for it), but the solution was simply to delete the folders named things like "file678418be" inside R/library. After doing this I had no problem, though. Go figure.

Cheers,

Jay
