[R] restrictions for attribute access <Watchdog: Virus checked>

Hello everybody,

I have a problem with accessing class attributes. I think it might be due to namespace access restrictions or something similar, but I'm unable to figure it out, maybe someone knows the trick how to do it ...

I'm trying to extract some information from the summary object for a model fitted using the lmer function from the lme4 package:

  smry <- summary(lmer(foo ~ bar ...))
  tab <- attr(smry, "AICtab")
  tab$AIC

When I run this code as a regular R script everything works fine, tab$AIC has the desired value. But when I try to run this code from within a package I wrote, tab$AIC is NULL.

I've tried adding "import(lme4)", "importClassesFrom(lme4)" and "importMethodsFrom(lme4)" into the NAMESPACE file of my package, but it didn't help, tab$AIC is still NULL.

Thanks for any kind of hint!

Best Regards
Ben
