[R-meta] clubSandwich for variance components

[Stefanou Revesz]

Dear Colleagues,

I have recently learned about the RVE estimation and the usefulness of
the clubSandwich package in this regard.

I read the documentation of the package, but I was unable to determine
which function or functions in the package provide the adjusted
estimates of variance components and possibly their confidence
intervals (if I'm not mistaken, these are the ones that are often
unreliable if left unadjusted)?

Thank you for your assistance,
Stefanou
