I am trying to move a model from Stata to R.
It is a linear regression model with about 90,000 indicator variables.

I want to fit a model with crossed random effects and heteroskedastic

when %in% is == (for two vectors of different lengths); what is the equivalent

a %in% b returns a logical vector, so
!a %in% b
returns its negation. See order of precedence in ?Syntax.

Dear Iurie,
"Pr(>F)" is the p-value for the test of the null hypotheses that the
population variances are equal. This is the typical format for labelling a
p-value in R output.
