logbookAdjustment: Adjust landings by logbooks

In StoXProject/RstoxFDA: Fisheries Dependent Analysis with RstoX

Adjust landings by logbooks

Description

imputes landings and redistributes catch within quarter and area to mimic sales notes for each individual fishing operation (logbook record). Applicable to formats parsed by readLssFile and readErsFile

Usage

logbookAdjustment(
  landings,
  logbooks,
  gearCodes = character(),
  speciesColLog = "FANGSTART_FAO",
  speciesColLand = "Art FAO (kode)",
  weightColLog = "RUNDVEKT",
  valueColLand = c("Bruttovekt", "Produktvekt", "Rundvekt"),
  addColumns = character(),
  activityTypes = c("FIS", "REL", "SCR"),
  polygons = RstoxFDA::mainareaFdir2018,
  lineIdCol = "Linjenummer"
)

Arguments

landings	landings as returned by e.g. readLssFile
logbooks	logbooks as returned by e.g. readErsFile
gearCodes	character() with NS-9400 gear-codes which logbook cleaning should be applied for. If not provided, cleaning is applied to all gear codes
speciesColLog	character() that identifies the column in 'logbook' that contain information about species of catch.
speciesColLand	character() that identifies the column in 'landings' that contain information about species of catch.
weightColLog	character() that identifies the column in 'logbook' that contain the weights that redistribution of weights should be based on.
valueColLand	character() vector that identifies the columns in 'landings' that contain values that are to be redistributed over imputed landings (weight and value columns)
addColumns	character() vector that identifies columns in 'logbooks' that should be added to 'landings'
activityTypes	character() vector with the activity types that should be utilized from logbook records ('AKTIVITET_KODE')
polygons	SpatialPolygonsDataFrame with area names in the column 'StratumName'. If provided, area ("Hovedområde kode") will be calculated from position, rather than fetched from logbook records.
lineIdCol	character() that identifies the column in 'landings' that contain the identifier for each line on a sales note.

Details

Imputes landings for logbook records, redistributes catches, and adds information from logbooks. See details in utilized functions: imputeCatchesLandings, sourceLogbookColumns, and addLogbookColumns. In particular consult sourceLogbookColumns to learn which columns in the 'landings' are affected by imputation.

Logbook imputations are only applied for logbook records with the gears in 'gearCodes' if given. If gearCodes are not given (the default) all available logbook records are applied.

Landings for which logbook records are not available, or not applied (by 'gearCode' restriction) are retained untouched in the returned landings.

Sales-note lines identifiers are made unique after imputation and redistribution ('lineIdCol').

Value

'landings' with catches redistributed over more sales-note lines corresponding to logbook-catch records / fishing operations.
