So RStudio unlocks the bindings and alters the exported environment? That seems
like another reason to stick to the terminal interface.

Thank you for letting me know. I hope I can avoid using private functions in
future. As noted below, my function seems to work now.

Now build.package works as written, so there?s nothing to debug. The problem may
have been that this package is so important to me that I put it in .Rprofile.
The package was not installed for the new version of R, so every R session
started with an annoying error message. Presumably a separate session started
with R CMD would just fail without installing the package. That?s no longer a
problem because the package is now installed. However, I don?t know why the
error message wasn?t clearer, and I?m puzzled that I was able to install
roxygen2 & devtools. Thank you everyone, and I?m sorry if I didn?t give the
right information to diagnose the problem faster.

Regards,
Jorgen.

This must be the solution to the mystery. I have recently added some
code that raised an error (lattice::standard.theme(...), but without a
new enough 'lattice' to understand the arguments) to my .Rprofile, and
it broke quite a few things related to package development until I fixed
my .Rprofile.

Congratulations on solving the problem!
