Thanks very much to Hadley and Prof. Ripley for their replies --
and my apologies to the list for failing to check my facts before I posted:
Prof. Ripley's reply was correct: system.file('rawdata',
package='testPackage') in a help page in package 'tstPackage' with
subdirectory 'inst/rawdata' returned
"~/Rpkgs/tstPackage.Rcheck/tstPackage/rawdata".
I was once again misled by something I knew that wasn't so.
Best Wishes,
Spencer

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.
There first part may or may not be true (it is not for some of the
ways 'check' is used on the check farm: consider the --install
argument, which is not described in --help), but in every case it will
be true that the copy of the package under check is installed in the
library at .libPaths()[1], and that installed package is used by
'check' unless the user's code does really odd things (like manipulate
.libPaths()).

Hello, All:
How can I obtain the location of an example data file in a package
during "R CMD check"?
I want to include sample raw data files in a package and have
them read
by a function in the package. It occurs to me to put such a file in
"\inst\rawdata" and have examples find the data using something like
"system.file('rawdata', package='MyPackage')". However, this will
only work
if the desired data are already in a version of 'MyPackage' that is
already
installed. If I change the data, this will return the old data, not
the
modified. I've looked at packages RUnit and svUnit, but have not spent
enough time with either to know if they include a solution to this
problem.
I doubt that the 'problem' is in 'R CMD check', but without a
reproducible example, we have no evidence either way. Certainly
plenty of packages use system.file() in their examples, and 'check'
works for them even if they are not previously installed.
Thanks for your help.
Spencer
