Thank you for responding.
I am truly grateful.
Apologies for omitting evident and pertinent information.

I am using 3.36.  I will update to 3.37.  I did not notice the newer version.

I realize I needed to be more specific.  The attr(, "var") that I am interested in is displayed with str(results) after the results object is declared.  First line of the subject code looks like:

results <- (if (multicore) parallel::mcapply else lapply)(uniques, function(i){....

How that line functions without error is beyond me, but minor to my objective.

Disclosing my prime goal, I am trying to produce the same values generated by the confint function, which receives the standard error values from this svyby function.  I am trying to replicate the standard error calculation in R and use it in a known program called Tableau.

If any other information is needed please let me know.

My sincerest gratitude.
