appendTripIdLogbooks: Assing trip ID to logbooks

In StoXProject/RstoxFDA: Fisheries Dependent Analysis with RstoX

Assing trip ID to logbooks

Description

Assings a trip ID to logbooks based on vessel identifier and a known last time of operation on a trip.

Usage

appendTripIdLogbooks(
  logbooks,
  tripIds,
  timeCol = "STARTTIDSPUNKT",
  vesselIdCol = "RC",
  tripIdCol = "tripid",
  verbose = T
)

Arguments

logbooks	data.table containing logbook records
tripIds	data.table with columns 'vesselId', 'time' and 'tripId'
timeCol	character() that identifies a POSIXct column in 'logbooks' that contain the time of operation for each logbook record. Default compatible with readErsFile.
vesselIdCol	character() that identifies a column in 'logbooks' that contain the vessel id (e.g. radio call signal) of the reporting vessel. Default compatible with readErsFile.
tripIdCol	character() that identifies the column name to append to 'logbooks'
verbose	logical() wheter to message progress

Details

'tripid' need not be complete in the sense that vessels not found in 'tripid' will be assigned a trip ID of NA, and any fishing operations after the last trip for a vessel will be assinged a trip ID of NA. This function will however assign all the fishing operations of a vessel preceeding the first trip time to the first trip.

Runnning time is proportional to the number of trips in 'logbooks', so it is advantagous to annotate after other relevant filtering.

Value

'logbooks' with the column identified by 'tripIDcol' added

Examples

 ## Not run: 
   #make trip ids from landings and assign them to logbooks
   lssfile <- "" #set appropriately
   logbfile <- "" #set appropriately
   landings <- RstoxData::readLssFile(lssfile)
   logbooks <- RstoxData::readErsFile(logbfile)
   tripIds <- makeTripIds(landings)
   logbooksWtripIds <- appendTripIdLogbooks(logbooks, tripIds)
 
## End(Not run)
