RE: [Rd] wishlist: better error message in R CMD check

I guess is that you did not try to run R CMD INSTALL before R CMD check. R CMD check will try to install the package first (in pkg.Rcheck), and only if that's successful would checks be done.

The installation process will concatenate all R files in R/ to a single file and essentially source() that in upon package loading. That's where you would see the syntax error. I believe the recommended way is to install the package and play with that a bit first, before doing R CMD check. You'd find some problems are much easier to find that way (e.g., errors in NAMESPACE). Cheers,
