Daniel,

I am not sure what you mean by "where to put the e(Row) to set the
rownames." Could you be more specific? To extract the rownames use
this command:

. local lclname : rownames e(Row)
. di "`lclname'"

See -help extended_fcn-. You would benefit from reading the entries
related to matrices in the Programming manual.
