ops_biblio: Process Multiple Lists of OPS Bibliographic Data (formerly...

In poldham/opsrdev: Access Patent Data with the European Patent Office "Open Patent Services" (OPS) API

Description

Use this function to process lists containing multiple lists of bibliographic data from OPS into a single data frame. Typically, the object will contain the results of multiple calls to OPS for bibliographic data in chunks of 100 records (see ops_urls()). For example, 10 calls will generate a single list containing 10 list objects each containing 100 records.

Usage

ops_biblio(x)

Arguments

x	A list of lists containing bibliographic data from OPS

Details

The function uses rapply and later aggregate. Note that aggregate will generate a warning. The use of fill() from tidyr is a temporary measure and is a likely source of weakness in the code. Note that in order to produce data.frames with an equal number of columns across all years the 'ipc' column for the historic IPC7 classification is presently dropped where present.

Value

a data.frame

Examples

## Not run: ops_biblio(ops_biblios)
