Format fields that specify the collection or catalog number of a specimen or occurrence record to a tibble using Darwin Core Standard.

In practice this is no different from using mutate(), but gives some informative errors, and serves as a useful lookup for fields in the Darwin Core Standard.

Usage

set_collection(
  .df,
  datasetID = NULL,
  datasetName = NULL,
  catalogNumber = NULL,
  .keep = "unused"
)

Arguments

.df

A data.frame or tibble that the column should be appended to.

datasetID

An identifier for the set of data. May be a global unique identifier or an identifier specific to a collection or institution.

datasetName

The name identifying the data set from which the record was derived.

catalogNumber

A unique identifier for the record within the data set or collection.

.keep

Control which columns from .data are retained in the output. Note that unlike dplyr::mutate(), which defaults to "all" this defaults to "unused"; i.e. only keeps Darwin Core columns, and not those columns used to generate them.

Value

A tibble with the requested fields added/reformatted.
