metadata,
data and processingLog. Only RBR devices
(logger[["time"]], where
the string could also be "pressure" or "temperature". Items
in metadata must be specifield by full name, but those in
data may be abbreviated, so long as the abbreviation is unique.
Assignment can be made with e.g. logger[["pressure"]] <- value,
etc.logger object may be read with read.logger or
created with as.logger. Plots can be made with
plot.logger, while summary.logger produces
statistical summaries and show produces overviews. If atmospheric
pressure has not been removed from the data, the functions
loggerPatm may provide guidance as to its value. Similarly,
if the record contains periods when the instrument was in the air,
loggerTrim may prove useful in isolating the times when it
was in the water. However, these last two functions are no equal to decent
record-keeping at sea.
