create_metadata: Create metadata template

Description

This function creates a metadata template to be used in format_columns() for formatting and standardizing column names and classes in occurrence datasets. All column names specified as arguments must be present in the occ dataset.

If you obtained data from GBIF, SpeciesLink, BIEN or iDigBio using the functions provided in the RuHere package, you do not need to use this function, as the package already includes metadata templates for these datasets.

Usage

create_metadata(
  occ,
  scientificName,
  decimalLongitude,
  decimalLatitude,
  collectionCode = NA,
  catalogNumber = NA,
  coordinateUncertaintyInMeters = NA,
  elevation = NA,
  country = NA,
  stateProvince = NA,
  municipality = NA,
  locality = NA,
  year = NA,
  eventDate = NA,
  recordedBy = NA,
  identifiedBy = NA,
  basisOfRecord = NA,
  occurrenceRemarks = NA,
  habitat = NA,
  datasetName = NA,
  datasetKey = NA,
  key = NA
)

Examples

# Load data example
# Occurrences of Puma concolor from the atlanticr R package
data("puma_atlanticr", package = "RuHere")
# Create metadata to standardize the occurrences
puma_metadata <- create_metadata(occ = puma_atlanticr,
                                 scientificName = "actual_species_name",
                                 decimalLongitude = "longitude",
                                 decimalLatitude = "latitude",
                                 elevation = "altitude",
                                 country = "country",
                                 stateProvince = "state",
                                 municipality = "municipality",
                                 locality = "study_location",
                                 year = "year_finish",
                                 habitat = "vegetation_type",
                                 datasetName = "reference")
# Now, we can use this metadata to standardize the columns
puma_occ <- format_columns(occ = puma_atlanticr, metadata = puma_metadata,
                           binomial_from = "actual_species_name",
                           data_source = "atlanticr")
