[R] Building Packages.

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.
