ensemble_qid_x_qid_table

PURPOSE ^

Produces a table comparing two question IDs.

SYNOPSIS ^

function an_st = ensemble_qid_x_qid_table(data_st,params)

DESCRIPTION ^

 Produces a table comparing two question IDs.
 an_st = ensemble_qid_x_qid_table(data_st,params);

 Produces a table in which the levels for one question ID form the columns and
 the levels for the other question ID form the rows.

 params.table.qid_order = compqid values specifying row, column order
 params.report.tables.print = should table be printed
 params.report.tables.write2file - should table be written to a file
