Those both look correct to me (but not the same). What do you see?

The second one looks wrong here (no escapes shown), but I suspect those inner quotes aren't really the same as the outer quotes, and that's why they're not escaped.

If you don't want the fancyquotes at all, you can use options(useFancyQuotes=FALSE). In a package, it would be polite to do this only locally, i.e. have something like

save <- options(useFancyQuotes=FALSE)
on.exit(options(save))

in functions that call sQuote or dQuote, because options() belong to the user, not to you.
