[Rd] Reading a specific file during "R CMD check"?

[Hadley Wickham]

Hi Spencer,

I think one of the early phases of R CMD check is R CMD install - it
installs the package into a special location so that it doesn't
override existing installed packages, but still allows function to
work exactly as if they were in an installed package.
