Details and Options

• ResourceFunction["name"] searches in order for a resource function with the specified name in the following locations:
• locally in the session (for resource functions from DefineResourceFunction) at the locations specified by $PersistencePath in the Wolfram Function Repository
• In ResourceFunction[resource], resource can have the following forms:
• "name"function name, resolved as described ResourceObject[…]a resource object of type "Function" stored at any location CloudObject[…]a cloud object containing a function resource object LocalObject[…]a local object containing a function resource object
• ResourceFunction[resource][args …] applies the function to the given arguments.
• The available properties are given by ResourceFunction[resource,"Properties"] and typically include properties of the ResourceObject as well as:
• "SymbolName"fully qualified string name of the underlying function "FunctionLocation"file, object or method used to store the definition "DocumentationLink"URL for documentation of a published function
• ResourceFunction accepts the following options:
• ResourceSystemPath $ResourceSystemPathwhere to look for a function ResourceVersion Automaticversion to select of a published resource
• Function definitions in a function resource are typically not explicitly retrieved until the function is used.
• When the definitions for a function resource are retrieved, they are usually cached in $LocalBase.
• ResourceObject[ResourceFunction[…]] returns the resource object containing the given function.
• ResourceFunction[ResourceFunction[…],prop] gives a property for an existing resource function.
• CloudDeploy[ResourceFunction[…]] or CloudPublish[ResourceFunction[…]] saves a resource function in the cloud.
• LocalCache[ResourceFunction[…]] saves a resource function as a LocalObject[…].
• The following functions work on ResourceFunction objects: Attributes, Definition, DownValues, FullDefinition, Options and SymbolName.
• New resource functions can be defined with DefineResourceFunction or with a definition notebook from File ▶ New ▶ Repository Item ▶ Function Repository Item.

Examples

Basic Examples  (5)

Get a resource function using its name:

Apply the resource function to arguments:

Apply a function from a ResourceObject to a value:

Find properties of a resource function:

Get the web documentation URL for a published function:

Create a resource function from an Association:

Scope  (7)

Use the two-argument from of ResourceFunction to retrieve properties:

Get a list of properties:

Obtain information on a resource function:

View basic usage:

Run all verification tests defined for a resource function to generate a TestReportObject:

A Missing object is returned for resource functions that do not have defined tests:

See all the tests defined for a resource function in a testing notebook:

See when a resource function was first published to the Wolfram Function Repository:

Get the date of the most recent update:

Get a list of available versions:

Options  (3)

ResourceSystemPath  (2)

Use ResourceSystemPath to limit the result to only find functions published in the function repository:

Create a new resource function with the same name as a deployed function:

Use ResourceSystemPath to ensure this resource is found:

Instead, find the published function:

ResourceVersion  (1)

Get two versions of the same resource from the function repository using ResourceVersion:

Only the newer version supports a zero-argument form:

Properties & Relations  (3)

The two-argument form of ResourceFunction provides the same values as ResourceObject:

The underlying symbol belonging to a ResourceFunction can be obtained using the "Function" property:

Using the symbol directly can often be faster:

Many functions that work on symbols also work on resource functions, for example, DownValues:

And Attributes:

And Options:

Possible Issues  (1)

Resource functions that have holding attributes will only hold arguments if ResourceFunction[…] is explicitly used as the head:

Use ResourceFunction[…][…] instead to ensure attributes will work:

Using the formatted form will also work:

Alternatively, set the symbol to the underlying function instead:
