show_values.Rd

Users may wish to see the specific values within a chosen field, profile or list to narrow queries or understand more about the information of interest. show_values() provides users with these values. search_values() allows users for search for specific values within a specified field.

Usage

show_values(df)

search_values(df, query)

Arguments

df

A search result from search_fields(), search_profiles() or search_lists().

query

A string specifying a search term. Not case sensitive.

Value

A tibble of values for a specified field, profile or list.

Details

Each Field contains categorical or numeric values. For example:

  • The field "year" contains values 2021, 2020, 2019, etc.

  • The field "stateProvince" contains values New South Wales, Victoria, Queensland, etc. These are used to narrow queries with filter() or galah_filter().

Each Profile consists of many individual quality filters. For example, the "ALA" profile consists of values:

  • Exclude all records where spatial validity is FALSE

  • Exclude all records with a latitude value of zero

  • Exclude all records with a longitude value of zero

Each List contains a list of species, usually by taxonomic name. For example, the Endangered Plant species list contains values:

  • Acacia curranii (Curly-bark Wattle)

  • Brachyscome papillosa (Mossgiel Daisy)

  • Solanum karsense (Menindee Nightshade)

Examples

if (FALSE) { # \dontrun{
# Show values in field 'cl22'
search_fields("cl22") |> 
  show_values()

# This is synonymous with `request_metadata() |> unnest()`.
# For example, the previous example can be run using:
request_metadata() |>
  filter(field == "cl22") |>
  unnest() |>
  collect() 

# Search for any values in field 'cl22' that match 'tas'
search_fields("cl22") |> 
  search_values("tas")

# See items within species list "dr19257"
search_lists("dr19257") |> 
  show_values()
} # }
