[R] Error in quantile.default(resids) : missing values and NaN's not allowed if 'na.rm' is FALSE

[Chad Danyluck]

About a year ago I ran some analyses using lmer. The general syntax was:

mlm <- lmer(var1 ~ (1|dyad) + var2 + var3*var4*var5, na.action=na.exclude);
summary(mlm)

The model ran fine and I saved the output. I've recently turned back to
those analyses, however, the model no longer runs. I get the following
error:

Error in quantile.default(resids) :
  missing values and NaN's not allowed if 'na.rm' is FALSE

I've searched the online forums and found that this topic has not been
touched upon since 2006, and at that time someone had indicated that it was
a bug that had been resolved. I am using the most current version of lme4,
so if the bug is fixed I am unsure why I am experiencing this problem.

I have since run the model using lmer's default for handling missing data
(na.omit), but found the results do not match what I had saved previously
when using na.exclude.

If anyone has an insight here I'd be very appreciative.

Kind regards,

Chad
