Details

'landings' should already imputed with information about individual catches. The columns 'tripIdCol' and 'catchIdCol' must be set on 'landings' and 'logbooks'. This may be achieved by appendTripIdLogbooks, appendTripIdLandings and imputeCatchesLandings.

'landings' may contain records with no correspond logbook entires ('tripIdCol' contains NAs). The added columns will have NA for these records.
