appendTripIdLandings: Assign trip IDs

In StoXProject/RstoxFDA: Fisheries Dependent Analysis with RstoX

Assign trip IDs

Description

Assigns trip IDs to landings based on vessel identifier and date of last catch.

Usage

appendTripIdLandings(
  landings,
  tripIds = NULL,
  vesselIdCol = "Radiokallesignal (seddel)",
  lastCatchCol = "Siste fangstdato",
  tripIdCol = "tripid"
)

Arguments

landings	data.table containing landings records
tripIds	data.table with columns 'vesselId', 'time' and 'tripId'
vesselIdCol	character() that identifies a column in 'landings' that contain the vessel id (e.g. radio call signal) of the landing vessel. Default compatible with readLssFile.
lastCatchCol	character() that identifies a POSIXct column in 'landings' that contain the time of last catch for each record. Default compatible with readLssFile.
tripIdCol	character() that identifies the column name to append to 'landings'

Details

if 'tripIds' is NULL, trip IDs will be constructed from landings using makeTripIds

Value

data.table with columns 'vesselId' and 'time'

Examples

 ## Not run: 
   #merge mesh size from first operation on a trip into landings
   lssfile <- "" #set appropriately
   logbfile <- "" #set appropriately
   landings <- RstoxData::readLssFile(lssfile)
   logbooks <- RstoxData::readErsFile(logbfile)
   tripIds <- makeTripIds(landings)
   logbooksWtripIds <- appendTripIdLogbooks(logbooks, tripIds)
   landingsWtripIds <- appendTripIdLandings(landings, tripIds)

   firstCatch <- logbooksWtripIds[!duplicated(logbooksWtripIds$tripid),]
   landingsWmeshSize <- merge(landingsWtripIds,
                              firstCatch[,c("tripid", "MASKEVIDDE")],
                              by="tripid",
                              all.x=T)
