search_data: Search published data

Description

Search published data

Usage

search_data(text, taxa, num_taxa, num_years, sd_years, area, boolean = "AND")

Value

(tbl_df, tbl, data.frame) Search results with these feilds:

• source - Source from which the dataset originates. Currently supported are "EDI" and "NEON".

• id - Identifier of the dataset.

• title - Title of the dataset.

• description - Description of dataset. Only returned for NEON datasets.

• abstract - Abstract of dataset.

• years - Number of years sampled.

• sampling_interval - Standard deviation between sampling events in years.

• sites - Sites names or abbreviations. Only returned for NEON datasets.

• url - URL to dataset.

• source_id - Identifier of source L0 dataset.

• source_id_url - URL to source L0 dataset.

Arguments

text

(character) Text to search for in dataset titles, descriptions, and abstracts. Datasets matching any exact words or phrase will be returned. Can be a regular expression as used by stringr::str_detect(). Is not case sensitive. Works with boolean.

taxa

(character) Taxonomic names to search on. To effectively search the taxonomic tree, it is advisable to start with specific taxonomic names and then gradually broaden the search to higher rank levels when needed. For instance, if searching for "Astragalus gracilis" (species) doesn't produce any results, try expanding the search to "Astragalus" (Genus), "Fabaceae" (Family), and so on. This approach accounts for variations in organism identification, ensuring a more comprehensive exploration of the taxonomic hierarchy.

num_taxa

(numeric) Minimum and maximum number of taxa the dataset should contain. Any datasets within this range will be returned.

num_years

(numeric) Minimum and maximum number of years sampled the dataset should contain. Any datasets within this range will be returned.

sd_years

(numeric) Minimum and maximum standard deviation between survey dates (in years). Any datasets within this range will be returned.

area

(numeric) Bounding coordinates within which the data should originate. Accepted values are in decimal degrees and in the order: North, East, South, West. Any datasets with overlapping areas or contained points will be returned.

boolean

(character) Boolean operator to use when searching text and taxa. Supported operators are: "AND", "OR". Default is "AND". Note, other parameters used in a search are combined with an implicit "AND".

Details

Currently, to accommodate multiple L1 versions of NEON data products, search results for a NEON L0 will also list all the L1 versions available for the match. This method is based on the assumption that the summary data among L1 versions is the same, which may need to be addressed in the future. A list of L0 and corresponding L1 identifiers are listed in /inst/L1_versions.txt. Each L1 version is accompanied by qualifying text that's appended to the title, abstract, and descriptions for comprehension of the differences among L1 versions.

Examples

if (FALSE) {
# Empty search returns all available datasets
search_data()

# "text" searches titles, descriptions, and abstracts
search_data(text = "Lake")

# "taxa" searches taxonomic ranks for a match
search_data(taxa = "Plantae")

# "num_years" searches the number of years sampled
search_data(num_years = c(10, 20))

# Use any combination of search fields to find the data you're looking for
search_data(
  text = c("Lake", "River"),
  taxa = c("Plantae", "Animalia"),
  num_taxa = c(0, 10),
  num_years = c(10, 100),
  sd_years = c(.01, 100),
  area = c(47.1, -86.7, 42.5, -92),
  boolean = "OR")
