Result objects

Outputs from nearly all rdatacite functions will be of class dc, an S3 class that's simply a named list of results. You can easily remove the class via unclass(). The print.dc method prints the data.frame for the data, included, and reports slots if they exist, but hides the meta named list. You can get to the metadata by indexing to it like $meta.

Searching

You may want to start with dc_dois().

The query parameter supports Elasticearch query string queries. Some examples:

# search within a field
dc_dois(query = "publicationYear:2016")
# fuzzy search (via *) on a nested field
dc_dois(query = "creators.familyName:mil*")
