Removing an agent or an informant's association to a table-pre formula can be done with remove_read_fn(). This may be good idea in an interactive session when needing to rely on the direct association of a 'fixed' data table (settable in create_agent() and create_informant()'s tbl argument or with set_tbl()) instead of using a table-prep formula that might produce different a different table than expected. The table-prep formula can always be set again with set_read_fn().




An agent object of class ptblank_agent, or, an informant of class ptblank_informant.
