An example of ideal metadata formatting for a sample set run on the Aqualog

Many of the functions within the 'fewsdom' package require metadata for smooth use with the functions it is recommended to use this sample as a template for the metadata.

Usage

meta

Format

a data frame with 8 rows and 11 columns:

index

The numeric order of entry (e.g. 1, 2, 3, 4, etc…)

analysis_date

The date the samples were run on instrument (not collected in the field)

description

A brief description of the sample collected 60-character max, used for plot titles

data_identifier

the data identifer for the sample that was used in the Aqualog, needs to be exact

replicate_no

A numeric denoting analytical duplicates. They must have identical Sample identifiers

integration_time_s

Integration time of the sample (e.g. 1, 2, etc…)

dilution

Include the dilution factor here as decimal format (e.g. a 2-fold dilution with 1 part sample and 1 part water will have a dilution factor of 0.5). No dilution is a 1

RSU_area_1s

The RSU Adjust Area from the Raman Test

run_type

How the sample was run, should be either "SampleQ" or "Manual", used to rename and organize samples

DOC_mg_L

DOC concentration in mg/L of the original sample (not the diluted sample)

Notes

Not required, but can be used to note abnormal sample or experimental conditions
