Dear John, et al.:
What happens if lme4 is loaded before the effect package?
Is this an issue of a user wanting to use two different packages
with potentially conflicting names? What are the standard
recommendations for handling issues like this? Just to test my
comprehension, I assume that the key is that users should routinely
watch for warnings of name conflicts and follow the advice of sect.
"1.6.1 Specifying imports and exports" of "Writing R Extensions" when
that occurs? (This is another reason for writing R packages and using
namespaces, so users can record appropriately what they want in
situations like this and not have to worry about name conflicts later?)
Thanks,
Spencer

Dear Michael,
effect() works with lmer(). Just load lme4 after the effect package. See the
penultimate example in ?effect.
I hope this helps,
John

Hi,
I would like to use the effect() function (actually a slightly modified version
of it) on the output of the lmer() function in the lme4 package. But the
effects package requires the nlme pacvkage, which is incompatible with lme4.
Workaround?
