Fill in values from logbooks

Fills selected columns in imputed landings from corresponding logbook records

Usage

sourceLogbookColumns(
  landings,
  logbooks,
  tripIdCol = "tripid",
  catchIdCol,
  speciesColLand = "Art FAO (kode)",
  speciesColLog = "FANGSTART_FAO"
)

Arguments

landings

data.table containing landings records, and columns identifying the trip and catch ('tripIdCol', 'catchIdCol').

logbooks

data.table containing logbook records, and columns identifying the trip and catch ('tripIdCol', 'catchIdCol').

tripIdCol

character() that identifies the column in 'landings' and 'logbooks' that contain trip ids

catchIdCol

character() that identifies the column in 'landings' and 'logbooks' that contain catch ids

speciesColLand

character() that identifies the column in 'landings' that identify species landed

speciesColLog

character() that identifies the column in 'logbooks' that identify species caught.

Details

The following columns in 'landings' may be altered. All others are left untouched:

Hovedområde (kode)

set to corresponding value in logbooks

Hovedområde

set to NA for landings with corresponding entries in logbooks

Lokasjon (kode)

set to corresponding value in logbooks

Siste fangstdato

set to corresponding value in logbooks

Redskap

set to corresponding value in logbooks

'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.

The function sets values for gear, area codes, and date of last catch from logbooks. Landings that does not have corresponding logbook records are left untouched
