Identify records from doubtful source (e.g., 'fossil', MachineObservation')

This function flags records with an informed basis of records (i.e., therecords type, for example, a specimen, a human observation, or a fossilspecimen) not interpretable, which does not comply with Darwin Corevocabulary, or unreliable or unsuitable for specific analyses.

Arguments

A data.frame containing the column ".basisOfRecords_notStandard".Compliant (TRUE) if 'basisOfRecord' is standard; otherwise "FALSE".

Details

Users are encourage to select the set of basis of records classesto keep. Default = c("Event","HUMAN_OBSERVATION", "HumanObservation","LIVING_SPECIMEN", "LivingSpecimen", "MACHINE_OBSERVATION","MachineObservation", "MATERIAL_SAMPLE", "O", "Occurrence","MaterialSample", "OBSERVATION", "Preserved Specimen","PRESERVED_SPECIMEN", "preservedspecimen Specimen", "Preservedspecimen","PreservedSpecimen", "preservedspecimen", "S", "Specimen", "Taxon","UNKNOWN", "", NA)
