Re: [R] Packages 'effects' loads 'name' which conflicts with 'lme4' [corrected subject: Package 'effects' loads 'nlme' which conflicts with 'lme4']
Dear John, et al.: What happens with import(foo) and importFrom(foo, f, g) with foo in suggests? Does foo appear in the search path? If no, then it may be wise to specify all uses in package mine of objects from package other using import and importFrom with other in suggests. If this is accurate, then users of mine will never have to worry about secondary conflicts like effects using name from either nlme or lme4: The use of name from nlme in effects will not cause nlme to be loaded. That means that it won't matter to effects whether and where lme4 is loaded, and it won't matter to the user, either. Might it be good to modify section 1.6.1 Specifying imports and exports of Writing R Extensions to make this clear? I just read it now, and it seemed quite clear to me except for this point.

Re: [R] Packages 'effects' loads 'name' which conflicts with 'lme4' [corrected subject: Package 'effects' loads 'nlme' which conflicts with 'lme4']
Dear Spencer, Perhaps I misunderstand what you suggest, but I don't see how importing objects helps, when there are objects of the same name in both nlme and lme4 that users of effects will use in different circumstances. That is effect.lmer() and effect.lme() should both work, though not in the same session. The solution I'm implementing is to put both lme4 and nlme in Suggests: and to require() each as needed, presumably not in the same session, when the package loaded second would mask functions in the package loaded first. I'm sure that there are circumstances where this solution isn't appropriate, but I think that it suffices for the effects package.

Re: [R] Packages 'effects' loads 'name' which conflicts with 'lme4' [corrected subject: Package 'effects' loads 'nlme' which conflicts with 'lme4']
Hi Spencer, In an Sweave script, which would take me too long to boil down to a reproducible example, lme4 was loaded before effects, and a calculation involving the effect() function failed. This was remedied by following John's advice and loading the two packages in the order he recommended at the beginning of the run. The problem went away. As far as I can tell, no such warning was issued, or at least none was noticed by me, because I'm caching many computations, which may hide warnings.
