I am working on a package where Enhances field seems to be a plausible option. When I add package, say coda, to this field, I get the following warning with recent R-devel:

See the information on DESCRIPTION files in the chapter 'Creating R packages' of the 'Writing R Extensions' manual.

I have require(code) somewhere in the code. Is this OK or is R CMD check to stringent in case of enhances field - I get no warning if that package is in depends or suggests fields?

After a short look into src/library/tools/R/QC.R I think that the following might be the solution. I did not do any other testing than with my package, where R CMD check (R with proposed change) passed without warnings.
