rrefine (version 2.1.0)

refine_operations: Apply operations to OpenRefine project

Description

This function allows users to pass arbitrary operations to an OpenRefine project via an API query to /command/core/apply-operations. The operations to perform must be formatted as valid JSON and passed to this function as a list object.

Usage

refine_operations(
  project.name = NULL,
  project.id = NULL,
  verbose = FALSE,
  operations,
  ...
)

Value

Operates as a side-effect passing operations to the OpenRefine instance. However, if verbose=TRUE then the function will return an object of the class "response".

Arguments

project.name

Name of project

project.id

Unique identifier for project

verbose

Logical specifying whether or not query result should be printed; default is FALSE

operations

List of operations to perform

...

Additional parameters to be inherited by refine_path; allows users to specify host and port arguments if the OpenRefine instance is running at a location other than http://127.0.0.1:3333
