vetiver_create_meta: Metadata constructors for 'vetiver_model()' object

In tidymodels/vetiver: Version, Share, Deploy, and Monitor Models

Metadata constructors for vetiver_model() object

Description

These are developer-facing functions, useful for supporting new model types. The metadata stored in a vetiver_model() object has four elements:

• ⁠$user⁠, the metadata supplied by the user

• ⁠$version⁠, the version of the pin (which can be NULL before pinning)

• ⁠$url⁠, the URL where the pin is located, if any

• ⁠$required_pkgs⁠, a character string of R packages required for prediction

Usage

## S3 method for class 'train'
vetiver_create_meta(model, metadata)

## S3 method for class 'gam'
vetiver_create_meta(model, metadata)

## S3 method for class 'keras.engine.training.Model'
vetiver_create_meta(model, metadata)

## S3 method for class 'kproto'
vetiver_create_meta(model, metadata)

## S3 method for class 'luz_module_fitted'
vetiver_create_meta(model, metadata)

vetiver_meta(user = list(), version = NULL, url = NULL, required_pkgs = NULL)

vetiver_create_meta(model, metadata)

## Default S3 method:
vetiver_create_meta(model, metadata)

## S3 method for class 'Learner'
vetiver_create_meta(model, metadata)

## S3 method for class 'ranger'
vetiver_create_meta(model, metadata)

## S3 method for class 'recipe'
vetiver_create_meta(model, metadata)

## S3 method for class 'model_stack'
vetiver_create_meta(model, metadata)

## S3 method for class 'workflow'
vetiver_create_meta(model, metadata)

## S3 method for class 'xgb.Booster'
vetiver_create_meta(model, metadata)

Arguments

model	A trained model, such as an lm() model or a tidymodels workflows::workflow().
metadata	A list containing additional metadata to store with the pin. When retrieving the pin, this will be stored in the user key, to avoid potential clashes with the metadata that pins itself uses.
user	Metadata supplied by the user
version	Version of the pin
url	URL for the pin, if any
required_pkgs	Character string of R packages required for prediction

Value

The vetiver_meta() constructor returns a list. The vetiver_create_meta function returns a vetiver_meta() list.

Examples

vetiver_meta()

cars_lm <- lm(mpg ~ ., data = mtcars)
vetiver_create_meta(cars_lm, list())
