Link media metadata to flight logs

Read all flight logs in a given folder and merge with data from a selecVideos() or selecAudios() data frame by time.

linkMetadataToFlight(
  ROOTfolderpath = NULL,
  flightlog_extension = ".srt",
  selected_videos = NULL,
  flightlog_datetime = NULL,
  timezone = NULL,
  melt = FALSE,
  ...
)

Arguments

ROOTfolderpath	full path to folder where all the flight logs to be processed are at (without a final slash). E.g. '/Users/you/Desktop'

...	If flightlog_extension = ".csv", arguments are passed down to read.csv().If flightlog_extension = ".SRT", arguments are passed down to read.table()
