On Windows, you can also use win-builder to prepare a package. On either the
Mac or Windows you can also do it locally.

Then look into drat (eg at http://dirk.eddelbuettel.com/code/drat.html) to
see how super-easily you can set up and host a 'R repository' (ie like CRAN)
at GitHub (or if you prefer, locally). We use both at work to supply some
'public but not on CRAN' as well as local/non-public packages.  Note that you
still need to build the binary packages---but with drat it becomes
install.packages() as usual.

I understand that.  But it is not the Rcpp team's fault that Windoze ships
without a compiler (or that R does not include Rtools).  It is what is it,
and (literally) tens of thousands of developers have learned to cope within
these constraints.

Yes. I think years ago R CMD build had an option for that too.

| build when generating a binary package.

Yes.  I believe this is all documented in either Writing R Packages, or R
Installation and Administration, and both came with your R installation.

Good to know you have it all working, so we can close this now.
