Function checking the presence of quasi-identical records.

Description

Two or more "quasi-identical records" occurred when all the fields are respectively equal, except: TYPE_OF_FILE, AREA, GEAR, VESSEL, YEAR, RIGGING, DOORS, for TA table; TYPE_OF_FILE, AREA, VESSEL, YEAR for TB and TC tables.These specific fields are allowed to be identical.

Usage

check_quasiidentical_records(Result,year,wd,suffix)

Arguments

Result	Haul data table according to MEDITS protocol (TA), or Catch data table (TB) or Biological data table (TC).
year	reference year for the analysis
wd	Working directory selected by the user.
suffix	Suffix string of the Logfile.

Details

The checks always returns TRUES generating warning messages in the logfile if any quasi-identical record was found. In a given survey the following fields (of TA table) should be identical: 'TYPE_OF_FILE', 'AREA', 'VESSEL', 'GEAR', 'RIGGING', 'DOORS' and 'YEAR'. The function checks whether any differences occur in these fields in each yearly survey. The same think is done for all the other tables where these fields occur.

Value

The function always returns TRUE reporting the presence of quasi-identical records in the logfile.
