No example data, so no efforts at running code.

?panel.bwplot

# Notice the Usage at the top of the page. The "..." is there for a reason.

# And notice that neither 'do.out' nor 'coef' are passed in the "stats" list

# The message was talking about what arguments your 'mystats' would accept, .... not what it would return. It's another instance of your needing to understand what the "..." formalism is doing.

?boxplot.stats

# I would be making a concerted effort to return a list with exactly the components listed there.
