extract_claims {WikidataR} | R Documentation

## Extract Claims from Returned Item Data

### Description

extract claim information from data returned using `get_item`.

### Usage

    extract_claims(items, claims)

### Arguments

`items` | a list of one or more Wikidata items returned with `get_item`.
`claims` | a vector of claims (in the form "P321", "P12") to look for and extract.

### Value

a list containing one sub-list for each entry in `items`, and (below that) the found data for each claim. In the event a claim cannot be found for an item, an `NA` will be returned instead.

### Examples

    adams_data <- get_item("42")

    # Get claim data
    claims <- extract_claims(adams_data, "P31")
