Checks for the correct ordering of the data: increasing for date.and.time and time.since start, decreasing for fresh.weight and water.potential. Done separatly for each sample. An individualized warning is printed if not ordered correctly.
OrderCheck(data, sample = FALSE, date.and.time = FALSE,
fresh.weight = FALSE, water.potential = FALSE,
time.since.start = FALSE)data frame containing the data to be checked
